So are you using the binary driver? I think the Catalyst control centre has
options for this. Failing that, you may well have to modify your xorg.conf.
If you don't have one, running 'Xorg -configure' as root will save a default
configuration file to /etc/X11/xorg.conf; you need the right metamode option
in the 'Screen' section for the resolution you want.
For reference, mine looks like this:
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
Option "metamodes" "1920x1200 +0+0; 1024x768 +0+0; 800x600
+0+0; 640x480 +0+0"
SubSection "Display"
Depth 24
EndSubSection
EndSection
(Don't know why it mentions the colour depth twice; I suspect it's not really
needed. Also I believe the '+0+0' parts are the default and hence unnecessary)
