The Ubuntu Forums link noted by Dan Estberg appears to describe exactly
the same symptoms, but in one of the reported occurrences the video
driver in use was nvidia.

I have noticed that when I play AisleRiot Solitaire the Memory Utilization panel applet shows the memory utilization approaching 100% as I continue to play games. The main (or only) increment is in the "in use as cache" category. 
The memory resource graph in System Monitor does not show this component of memory usage. 

When I close and re-open AisleRiot, the memory utilization returns to
normal, and I have not had any xorg crashes yet as long I keep the
applet-displayed figure below 90% total.
