Hello,
Just upgraded to  10.8.2 and sleep works with plain DSDT if I wake the machine up via power button. Now I also have a DSDT that used to wakeup the machine via KB  in 10.7.5 but now if I use it for 10.8.2 the machine wakes up but blank screen. Any ideas?

ATI card ?
If it's, maybe you have to edit the framebuffer manually.

Hi,

Sorry forgot the system spec:

GA-P35-DS3L
Nvidia ( apple ) PEG
12 GIG RAM

Worked very well in 10.7.4 but 10.8 I am having issues.

I've met this before. But my hack in running on ATI card. As I've already said before, I had to modify ATIframebuffer to make it work.
I guess you may solve this problem by assigning correct value to Nvcap in dsdt.

double check power management settings in bios, since gigabyte they most likely got reset if you tried sleep without AppleRTC.kext patched. Patch AppleRTC.kext then use modified DSDT
