I am using the 10.6.7 kexts for IOPCIFamily and AppleACPI because even with the npci=0×2000 boot flag, I was stuck at PCI configuration begin. ATY_Init is completely unneeded btw, there is no difference.
You're right, ATY_Init is unneeded, so I got rid of it. I'm using the original IOPCIFamily and AppleACPI kexts from lion but also using the npci=0×2000 boot flag
I attached my kernel logs. Without the -f -v flags, running something that uses OpenGL gives me the following error:
NVDA(OpenGL): Channel exception! exception type = 0xd = GR: SW Notify Error
