OK, I think it's fixed in CVS.  Please tell me if it isn't.  I'd love to
get feedback from someone with specs for those AGP chipsets, or someone
with a v3 card, on the other half of the patch in the PR.

Also, anyone with DRI issues that involve hanging the system in things
not involving 3D, please tell me!  I'm very interested in getting these
stability issues fixed.
