Thanks for the advice. I downloaded Uphuck 10.4.9i r3 and installed it on my X61. The CPU SpeedStep app worked for about 2 min, but caused a kernel panic when I fiddled with the manual speed settings. It has not worked since and causes random kernel panics. Reinstall time.
No need to reinstall. Just remove the speedstep application from the startup applications list (System Preferences -> Users -> Login Items, I think).
About the audio driver: you're right that the X60 and X61 use different audio chips (HD1981 vs HD1984), which is quite a shame. The development version of ALSA has support for the chipset, which should get you sound working under Linux. A kernel patch is available if you built your ALSA into the kernel instead of using a module. http://www.thinkwiki.org/wiki/AD1984
Yes, I actually have audio in Linux. Unfortunately, the speakers themselves don't work (the internal headset jack does). I'm not too hopeful, but a cheap iMic is good enough for me.
There is QE support for the GMA X3100 in 10.4.10? I was not aware of that. I'll check it out and see if I can get a successful upgrade. Of course I'll let you know how I did it.
I was guessing, since 10.4.10 is the first full release to support the Santa Rosa-base Macs. Unfortunately, all of those use discrete graphics, so that's probably not the case yet. Need to wait until the MacBooks (not Pro) update to Santa Rosa, I'd guess.
I'm going to try getting the cursed Intel PRO/1000 ethernet adapter working. There's several older versions of the 825xx.kext on the InsanelyMac forums that appear to support previously non-working variants of the Intel PRO/1000. They're worth a try.
Good luck on that. I just use USB one for now (Linksys USB200M).
EDIT: 10.4.10 has a kext that supports the ICH8 chipset, but not the GMA specifically. With the ICH8 support you should be able to set the SATA controller to AHCI mode. Be aware that doing so may cause installed operating systems to cease functioning. Windows XP does not support AHCI on ICH8 without an additional driver.[/b]
Which 10.4.10 update did you use? I tried koolkal but hosed my install completely.
