Got some problems with Snow Leopard.
 

Ok.. I just installed Snow leopard and i boot with arch=i386 to get my network to work. ( Chameleon 2 RC4 )

Here are the kexts i have downloaded:
FakeSMC v2
OpenHaltRestart
PlatformUUID
NullCPUPM
Nvinject
VoodooHDA
PS2

Is there any other kexts i should download to get a fully working snow leopard?

Here are the problems i have:
Airport not working in 64bit. And airport losing networks after a while on 32Bit.
Getting Sleep after Restart problems.
Slow Startup
Changing Achi to RAID problem.
Thats All!
