Mac 5870 sleep issue in Mountain Lion 10.8.4

[dakgiaw]

I have an ATI 5870 from a Mac Pro in my hackintosh running smoothly, except for sleep.

The machine sleeps then when waking it won't turn on the main screen (DVI) the card's fan speeds up but nothing else happens.

The rest of the build is a GA-Z77N-WIFI with an i3-3225.

I am using the profile for an iMac 12,2 since when I tried using mac pro profiles boot resulted in a kernel panic (as expected, completely different cpu in the mac pros).

Everything else seems to work great, any suggestions on how to fix waking from sleep?

Have you tried booting with GraphicsEnabler=no?

I also sometimes have to turn off monitor 1,2 or 3 times before it shows desktop
