I can re-confirm that latest radeonhd-snapshot with full DRI+EXA does not have corruption problems with:
- Mouse cursor
- Certain GTK widgets (or small icons in KDE)
- Bitmap/unaccelerated fonts

(But as mentioned, it's generally slower than radeon when it comes to acceleration and Compiz. It's also apparently more unstable, as it just froze on me when I tested it with many windows).
