Just to update my own email, I upgraded to Ubuntu Intrepid Ibex (Alpha 4 and 
now 5) which includes Xorg 1.5 and new Radeon drivers. It now works "out of 
the box". I had tried Ubuntu 7.04 and 8.04, several Kernel versions and DRM 
changes, this is the first time it worked which would make it appear to be 
some sort of Xorg issue.
