I've never seen or heard of this problem myself, however, I did much of
the work on the DRI version of the savage DDX.  It's basically Tim's
1.1.27 driver with some bits from S3 and Xfree86's DDXes plus a bunch
of stuff I added.  Also the DRI version uses a tiled framebuffer
(needed for 3d) while the xorg and xfree86 versions use a linear fb. 
It may be an XAA problem or perhaps an issues with the way the bitmap
descriptors are setup (just guesses).  If it is XAA, see if you can
narrow down the problem to a specific XAA function.  To do this try the
XXNo... options in your device config.  see the xorg.conf og XF86Config
man pages for more.
