well, after going down as far as the official 1:6.7.195-1ubuntu2 xserver-xorg-video-ati from gutsy, it starts to look like a configuration issue (which I find somewhat hard to believe, although I did have a hard time reconfiguring the newer xorg correctly. Maybe a dependency was missing?). With the attached xorg.conf and the help of grandr I can get out of the clone mode and into a dualhead setup.
