Public bug reported:

Binary package hint: xserver-xorg-video-amd

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.
