Hmm.  The Radeon driver mode selection code was restructured during the 
RandR integration, it's quite possible that some mode lines aren't getting 
properly added. But, your log file seems to list 1600x1024 as a valid 
mode, so I'm a bit confused.  What does 'xrandr' list as valid sizes?

The current RandR support in the core server is limited to size changes; 
rotation and reflection would have entailed some more invasive changes to 
the acceleration code that seemed inappropriate at this point in the 
release cycle.

The log you enclosed showed the screen running at 16bpp; I assume setting 
the depth to 24 switches that to 32bpp?
