I experienced similar problems before.  In my case, this was due to
problems with cfbfillrect.c and cfbcopyarea.c.  

Geert wrote similar routines in the CVS version of fbtest.  I modified
them so they can be used as drop-in replacements for the kernel
framebuffer.  See the thread "Console Rotation" last month.
