Nvidia 8800GTS g92 error loop and screen blinking

[xbb]

While I play after a while my screen start blinking and I cannot do anything because It's like frozen but I can still move the mouse cursor, until I force a reboot.

 

While rebooting I see an infinite loop of this text (I always boot with -v):

The videocard is an 8800GTS g92 512MB

I boot with -x32 -pci0 -v

GraphicsEnabler Y

and efi string is injected in my current DSDT

 

Thanks

 

EDIT

While looking a bit more around I found this video...

This is what happens to me too while playing games.

 

So I guess it's a 10.6.4 issue
