DRI and OpenGL problem with GM965

[Jesse Barnes]

Well, I'm not sure I was seeing the same problem as Svetlana.  I was seeing 
hangs when dragging glxgears around my desktop too fast.  With the latest 
bits as of last week however (pre-i915 unification) I wasn't able to 
reproduce the problem anymore...
