for some reason the xserver is picking a random mode rather than one of the
modes in the edid.

(II) RADEON(0): Output DVI-1 connected
(II) RADEON(0): Output DVI-0 disconnected
(II) RADEON(0): Output S-video disconnected
(II) RADEON(0): Using sloppy heuristic for initial modes
(II) RADEON(0): Output DVI-1 using initial mode 1152x864

You'll want to override that in the monitor section.  If you have problems with
2560x1600, try 1280x800 next.
