Please note that I've logged a ticket in Launchpad, but thought it best to
report here also. Please let me know if you need anything else to get to the
bottom of this. 

This issue does appear to have occurred when the Radeon fence functions were
changed between 2.6.32.x and 2.6.33. I'm afraid that I'm not terribly au fair
with memory barriers and debugging GPU lockup issues, but tell me what is
helpful in getting to the bottom of this matter as I can reproduce this every
time on the current kernel and I would like to help get rid of this problem.
