Comment # 17 on bug 20341 from 
Argh. So if it didn't crash with valgrind-mmt, it's a heisenbug :( Some silly
timing thing... and agpmode=0 either slows it down enough or it's something to
do with the GART. (I assume agpmode=0 -> 0 GART memory, yes?) In either case,
this is out of my (debugging) league. Thanks for doing the tests, and sorry
they didn't lead to anything easy. I'll leave this open, perhaps some brave
soul will delve into it.

Did you ever give nouveau.vram_pushbuf=1 a shot (without agpmode=0)?
