I have the same problem as mudhead. I'm running Ubuntu 10.10 AMD64 on a Dell T3500 workstation w/ ATI v5800 and 3 screens (1 rotated, 2 horizontal). I can use ATI Catalyst to rotate the display and work happily. I just have to un-rotate before shutdown so I can reboot later.
The open source driver has rotation problems, as well. It appears to to accept the command to rotate 1 of 2 displays (demanding a restart) but then quietly ignores the rotation request. I wonder if the root issue is memory management of the virtual area implied by the bounding rectangle for the whole set of displays whose area is now greater than the sum of the display areas. I note that the extra virtual space below the horizontal displays is treated differently in X11 than in Win7 (which works fine w/ my setup, sad to say). Win7 clips space at the bottom of the display. X11 lets stuff hang down into it. I have time, motivation and some skills to pursue these problems.
