Public bug reported:

I've got nouveau running on a 9500GT card, but having a problem using a
Modeline to create a resolution setting for my monitor. My monitor is
supposed to run at 1920x1200; however, it is detected at 1680x1050 from
EDID.  I have always (nvidia, nv, intel) had to workaround by using a
custom modeline setting and have been doing this for 2 years
successfully.

Nouveau works fine at the 1680 resolution; however, I cannot get nouveau
to work correctly at 1920 resolution, that the monitor is designed to
work at. When I use the modeline for 1920 below I can only see a tiny
(~1/4 inch) section of the screen at the top of the monitor.  It is big
enough to see the tip of the mouse moving around and some color from the
wallpaper, but not much esle.  It as if the whole bottom part is cut off
and black.  I can get out of this by switching to a Alt-Ctl-F1 terminal.

Any thoughts and Thanks, Geoff

My xorg.conf is below.
