The radeon driver does not correctly set the resolution in 6.12.2 or git as of
05-24-09. The native resolution for my monitor is 1280x1024 at 60 but radeon sets
it to 1024x1024. I can use cvt and xrandr and a Virtual line to set the correct
resolution, but since radeonhd correctly sets the resolution, I believe this is
a bug in radeon. Using xrandr to fix the resolution also causes many of the
fonts on the windows to be much smaller than normal, but I'm not sure if this
is related.

I have the following options set for radeon driver in xorg.conf :
 Option DDCMode "On"
 Option EnablePageFlip true
 Option AccelMethod EXA
 Option DRI on

I have had to add the following line in the Display subsection :
 Virtual 2048 2048

I am running slackware 12.2, but it's version of xorg isn't based on a specific
release, so I don't know what version to call it. I've upgraded mesa, libdrm,
and the kernel to versions 7.4.2, 2.4.11, and respectively myself. If
additional version info is needed, please request it. I can also attach
screenshots of my desktop from radeonhd and radeon if desired.
