Also I did a fresh install of 10.8
Then applied 10.8.3 and using certain tool (not sure if I can name it here), finished the setup with DSDT-Free Option, GraphicsEnabler=No, iMac12.2, plus other motherboard specific stuff. Ofcourse I set AtiCOnfig=Aji using CW.
Boots perfectly until white screen(s). Send it to sleep - wake up - and I am at desktop.
