I have a ThinkPad T61P Type 6459. JAS (10.4.8.) was an easy install, but the better things are in 10.4.10. I am dying for them to get Santa Rosa support, which is in 10.4.9 up so I tried Uphuck 10.4.9 1.4i r3. Didn't see my hard drive. I set the AHCI in the bios to compatibility and it worked. Installed easily. My upgrade to 10.4.10 was not easy. In digging and working (wayyyyyyyy too much time here) it appears that the Intel motherboard 965M santa rosa chipset is not in the current hackintosh builds

We will probably have to wait till 10.5 (Leopard) to get the goodies. So, a basic can it work install is OK. But there is no:
Wireless--Intel 4965AGN
Ethernet--Intel 825666M
Sierra Wireless mini-PCI (AT&T)--not hopeless as their is a fix for this on Linux, but first things first
Video--nVidia Quadro FX 570m (this is the G86 GPU that is next gen GeForce 8600 GT--the current MacBook Pro video cards) so it should be easy to get working, but the work has not been done
Bluetooth and firewire work. I have not messed around with sound as the graphics are the most important component to me. If I can get them going I plan on buying a compatible chipset (broadcom) mini-PCI card to replace my Intel one and simply have native Airport support. The cludgy hack for wireless support is simply not worth it.
After searching forever and trying many different things I have made some posts on osxscene.com and insanelymac.com. All posts under jharleman if you want to find them. If there is any progress let me know! I feel the pain. cheers - jl
