Installed using Easy Beast method. Audio didn't work afterwards but used the VoodooHDA package from code.google.com and audio is working. Was able to get graphics working via EFI Studios but I don't have Sleep working. Seems like each of us are having different issues.
I am not using a DSDT file (at least I did not generate one using Maldon's Auto Patcher).
Ah, you have a different rev. Mine is 1.0 which has a different audio chip IIRC.
I tried my edited DSDT as well patched one using Madlon's tool. Mine works better.
Do you have NullCPU kext installed?
