I've posted a few example pics of the corruption I see:

http://www.soudan.net/~bills/snapshot1.png - konq window w/ corrupted 
  menubar
http://www.soudan.net/~bills/snapshot2.png - gimp blown up version of 
  corruption

The corrupted regions are 14x22, with the exception of the one above
'hours'.  Each region is a well-formed horizontal gradient (!).

If the pitch was off while blitting from pixmap cache to framebuffer,
wouldn't the corruption just be garbage?  And a width of 14 seems like a
really odd size for a blit to me.

Maybe the problem then isn't with the blit from the pixmap cache to the
framebuffer, but it's that the pixmap cache itself is getting corrupted?
Jeff's memory management patch is looking fairly attractive.
