Please show your Xorg.0.log and the output of "xrandr -q".
You may have to set up custom modelines in xorg.conf, see
http://wiki.debian.org/XStrikeForce/HowToRandR12 for more information.

The fbdev driver will work with the nouveaufb kernel framebuffer. Boot
with video=1280x1024 to force the correct resolution for your monitor.
See http://nouveau.freedesktop.org/wiki/KernelModeSetting, section
"Forcing Modes".
