I have created this amazing work of art in your honor. I call it "gnu load":
So it can be that the freeze can be avoided by putting some x% gnu load on the gnu.

Don't know if this would work, but instead of using macpro 3,1 to avoid agpm, make it work for you by using 4,1 or 5,1 smbios and in agpupm.kext add your device ID under appropriate macpro model and change the Low Threshold; item0 value from zero to the same value as items 1-3.
It doesn't work, I tried everything, even several custom BIOS with altered power states provided by Rominator, both flashed to the card and loaded with Chameleon. I use MacPro3,1 so no AGPM, but I've tried with modified AGPM as well. The only thing that works consistently is keeping the GPU busy with something.
Thanks for anything you can do!
I meant the Fermi freezes, maybe I also need to downgrade to get no freezes anymore.
Freeze under what condition? I never get/got any freeze with my 9600 GT runnung most OpenGL tasks. But after 10.8.1/2 i cant run Unique Heaven Benchmark and some games like RAGE anymore. No probs with other OpenGL task, also OpenGL triangles can run forever without any freeze.
I know (from the past) that fermi gpus had some major freeze problems even running non OpenGL tasks like Flash/Safari & Co.
I think my freeze is a bit different.
