Can you all try with DRI and PCI GART instead of AGP GART ?

Also, Michel, what is X doing ? Is it always re-enabling AGP on wakeup ?
Is it making sure all ring processing is completely finished before
sleep ?

I know Darwin does some additional tweaking in the AGP driver during
sleep (basically disabling AGP), that might help to do the same here,
I'll try something.
