There are some memory management problem with the xorg VIA driver
together with EXA. What acceleration architecture are you using?

I intend to update the xorg via driver thoroughly in the not too distant 
Meanwhile you can check out the development trees at either (If you need EXA w render accel,  Accelerated 
mpeg2) (If you don't)
