[QUOTE]Glxgears and compiz work, but there are some graphical glitches with menus, buttons and typing text. Also busy windows become solid grey boxes. I'll see if I can catch all that in screen shots and file bugs[/QUOTE]

[QUOTE]
radeonhd seems somewhat slower at rendering glxgears than radeon. Both drivers report "IRQ's not enabled, falling back to busy waits: 2 18" while running the program[/QUOTE]

The upstream developers already know about a lot of these issues. Graphical glitches for R600/700 3D are expected right now. See: http://www.x.org/wiki/radeonhd%3Aexperimental_3D The key word is EXPERIMENTAL ;) I'm not sure how much more the code will stabilize before the Karmic code freeze. I'm guessing that Ubuntu will configure mesa with software rendering on R600/700 if they want things to be stable, even though it's slow.
