Could you try with xserver-xorg-video-ati 1:6.6.192-1 currently in
experimental in case it helps?

Or you feel more adventurous, you could try the randr-1.2 branch of the
upstream git repository since it should be better at discovering
modes/resolutions/... automatically without the need for anything in
xorg.conf. I have some packages of this somewhere if you want to try it.
