  Probably not related to those bugs, but XAA doesn't have a flag
to call the "sync function" for screen to screen copy after every
"sub blit" on hardware that has only 2 directions copy.

  There was a certain crash with the siliconmotion driver (smi 502)
a few seconds after opening youtube, due to the animations on the web
page overflowing the engine and locking the entire system.
Disabling xaa offscreen pixmaps caused it to do enough computations
to not overflow the engine...
  After changing the xaa code to ensuring the engine is idle before
every "subsequent screen to screen copy", the problem was corrected.
