Hi Mariusz,
First of all thank you so much for all your hard work and sharing everything with the rest of us! I have never used a Mac before so this was quite a challenge for me, but after working on this for about 12 hours yesterday I managed to get my E6400 up and running smoothly! I have the same setup as you with a P9600 chip. As I'm typing this I just noticed that it is not in your list. The problem I'm having is that I can't shut the computer down. Screen goes blank but the hard drive stays on. Everything is the same as your setup except for the chip and the WiFi card (i have the intel 5100). I am using your kexts and your latest dsdt.aml file (I replaced this on the USB stick prior to installation...it doesn't need to be replaced again right?). If you have any ideas as to why shut down won't work I'd love to hear it. Thanks again!
Gabor
