Sure, and sorry for posting patch that caused problems. We should have
test that better, but it's hard with that quite small community around
this driver :(

The patch you attached fixes issue on my P4M890. I've performed really
crazy operations with that and it seems to be really stable. Many
xrandr -s operations, Diablo II starting and even VT switching for
sure. My GPU didn't lock up.

So if you test this patch and won't find problem, would be nice to commit it.

Well, maybe you could just prefix all chipsets used in this patch with
"VIA_" string :) That would be much better to have driver that
compiles ;)
