Bug Description
Binary package hint: xserver-
GeodeLX with the video-amd driver does not support native resolutions of
wide monitors (1920x1200, 1680x1050, 1440x900, etc).
I have tracked it down to code in the LXValidMode() code that checks
each mode against the Cimarron table. This table only has standard VESA
resolutions (along with special ones for panels).

Jordan and I have been bouncing ideas back and forth about a patch for
this. The discussion is here. I hope to have a patch we both agree on
soon.
For now I am attaching a series of patches that fixes the problem for the
2.7.7.6 driver in my setup.

I figured out the issues in the original patch. Fix outlined on the geode mailing list:

Here is my test .deb for hardy:

With this driver running on my Linutop connected to an ACER x243w (24") I can get resolutions of 1920x1200, 1680x1050, 1440x900. None of these worked before the patch.
Please report if it worked/didn't work for you. It would be interesting to get your hardware configuration also, including monitor.
