The screen it's forwarded to is Linux with gallium intel drivers, fwiw. 
Wine appears to be the only way to crash ati drivers, actually I've had 
great experiences thus far with xf86-video-ati otherwise, i.e. never 
crashed and seems to have good performance for the card (it's a 4650, so 
well into the "supported" category).

The behavior sounds quite similar to the problem the nvidia-patch.sh 
script seems to be fixing for nvidia users. I'll take another look at 
it, but I think it's doing something with libGL.so...

Something makes me think it's a bug in running wine on amd64 that is 
triggering an X bug, i.e. x shouldn't crash here, but also wine is doing 
something wrong to crash X whether ATI or intel drivers. I don't have an 
nvidia card to test with unfortunately.
