This post has nothing to help with your resolution issue, rather it
addresses the other problems you're likely to have with your ATI card.
I have been working on mine all day, and here's the best howto I found
to get DRI working properly:

Check out the glxgears numbers I get now:

root at hly19809lx:/usr/src/linux# glxgears 
13359 frames in 5.0 seconds = 2671.735 FPS
13725 frames in 5.0 seconds = 2744.933 FPS
13706 frames in 5.0 seconds = 2741.110 FPS
13738 frames in 5.0 seconds = 2747.431 FPS

I was getting 150 FPS before.

Incidentally, I have the following card, and it is doing 1680x1050
with no funny stuff in xorg.conf.  But my Xorg.0.log shows it as a
perfectly normal video mode.  Sorry I can't help with this one.
Perhaps "future" means a future release of the radeon driver?  The
only other alternative would be a future version of the card, which
would be bad news.

There is a kernel driver called fb_radeon, and also an Xorg module
called xf86-video-ati which provides a module called radeon.  You want
the radeon driver from xorg.  Don't even build the fb_radeon module,
or it may try to load, and then conflict with the radeon driver.  I
build only the vesa module for emergencies.
