Check this guide for p-states and c-states. If you don't have p-states, means no real SpeedStep for you. Also, MBP1,2 is not really similar to our T60p, ours is more similar to MBP2,1 or MBP2,2.

I am using VoodooHDA from here http://www.projectosx.com/forum/index.php?showtopic=355
i do not care about microphone

i have an older CPU in my box...it does not even support 64bits
there is no link posted there

No tearing and I have resolution change ability. it took me a LONG time to get the EFI string just right.
You should try it out.

Ok, you're now officially my hero! It bloody works perfectly! I cannot believe it! And the most important thing, it works in x64! Now I have all hardware drivers enabled in x64! Unbelievable!

Initially I had display artefact where everything sort of duplicated with flickering, like with a bad refresh ratio on old CRT monitors. When I changed resolution to something lower and then back - artefact disappeared, but it was back after reboot. I had to extract your EFI and add my EDID there to make it work.

Thank you again, the solution is wonderful. I don't know how I missed ATI1600Controller. I didn't even know it existed!

@ Silencer, you'll be a legend around these parts if you complete an A through Z how-to on every step to making this work on a T60P with the V5200. Ref your first post ... complete the puzzle.

The only small problem is that skype sounds (not speech, only the sounds it plays when skype is started or a contact comes online) are a bit broken. Everything else is great. Plus sleep seems to work with this driver - though not fully working on my system because i think i need radeonhd.kext (madchicken version from here: http://www.insanelymac.com/forum/index. ... pic=190586 ), which fails to turn the display back on after sleep.

Does anyone have a solution for getting ati mobility X1400 to work without radeonhd? Can I use an Injector or EFI string to turn on the internal display? Did anyone find a solution for this?

What do you mean by "fails to turn on display after sleep"? Does sleep lid indicator (small half-moon) stays on after you try to wake up?

From what I've read about X1400, you are stuck with RadeonHD. There's no other even remotely better solution.

No, the system fully resumes. No half moon. Full HDD activity, sound and everything. Just a black screen. I reported bugs to the Google Code page of RadeonHD, but no reply yet.

Well. For now, I have to live with these small quirks then. Thanks anyway for the fast reply - it is so hard to find this information. Everything is only documented in forums, sometimes in foreign languages. It's hard to keep track of it all.

Oh my, I hate to be the only one with the Sleep problem Can you please upload your VoodooHDA.kext somewhere? Also, where do you have it, in /E/E or in /S/L/E?

Anyways, it's good that you have at least RadeonHD, because sometime ago there was nothing for X1400. RadeonHD is a great project, although it is not widely developed, which is a real shame.

Scratch that, looks like the problem is not in EDID. Image flickering appears when I try to boot with Refresh Rate set to 60Hz. If I switch it to 50Hz, it works fine.

plastikman, can you please check which Refresh Rate you have and if it is set to 50Hz, try to boot with 60Hz?

Also, as far as I understand, you have Sleep working fine with VoodooHDA. This is another mystery to me, because I never managed to wake my T60p up when using VoodooHDA. Can you please compile and upload the full /Extra contents and any kexts you have in /S/L/E? Also, if possible, post a dump of your kextstat and full dump of IORegistryExplorer. I really want to compare your and mine to see what can I do about Sleep.

i posted all kexts that i have in /E/E earlier and i am only using voodoohda and lidsleep in /S/L/E

I tested on 60 HZ and see exactly what you are talking about.
50 HZ is just fine.

plastikman, I've noticed another minor problem with ATI1600Controller. It reduces brightness one level down after some time. It is almost random, but rather annoying. Do you have similar problem?

Yes I have the same issue...I am not sure how to resolve it either since in the BIOS I have set my configuration to always be bright. Maybe the efi string needs to be tweaked? I had not spent much time on it as I am OK with just hitting the brightness keyboard shortcut

It looks like the fix for bad temperature was an easy one. I've checked in MSR Tools, and speed step was not working - always max frequency (2.33GHz).

Then I've checked the difference between my legacy kext (block ACPI_SMC_PlatformPlugin/IOPlatformThermalProfile) and /S/L/E/IOPlatformPluginFamily.kext/Contents/PlugIns/ACPI_SMC_PlatformPlugin.kext/Contents/Resources/MacBookPro2_1.plist which is the one I use as a reference. And the difference was in CtrlLoopArray/0/StepDataDict/SP1 block. It is usually the same across all models, but it was changed in 10.6.3. After update and restart temperature has fallen back to normal.

Heh... this has been stopping me from updating to 10.6.3, how exactly do I apply this fix?

Console gives a whole bunch of output, referencing FakeSMC (something about a key not being found) and the reason for waking as being "USB1 USB7", whatever that means.

Hmmm, I've already got a patch in there. It's the same one from your guide, however the patch from the ProjectOSX link shows different code with different values. Is the code in your guide an older fix?

Not sure if I should just copy/paste the whole thing (code from ProjectOSX) in there or not. I'll probably wait till you've sorted everything out first.
