>(II) RADEON(0): Max desktop size set to 2560x1600
>(II) RADEON(0): For a larger or smaller max desktop size, add a Virtual line to >your xorg.conf
>(II) RADEON(0): If you are having trouble with 3D, reduce the desktop size by adjusting the Virtual line to your xorg.conf

Is a (maximum) desktop size of 2560x1600 really required? Lately the
xorg-x11-drv-ati module wants to allocate enough texture memory for the
absolute largest desktop it could possibly support. Maybe if you added a
Virtual directive your problems might be solved:

>(II) RADEON(0): Output DVI-0 using initial mode 1680x1050

Probably this is the maximum size you need. This solved some crashes for my
case (RC410 with 64Mb VRAM).
