At work, I have an old Dell monitor that doesn't do EDID, and I can't get nouveau to do anything better than 1024x768 on it even if I use system-config-display to tell it that the monitor is a 1920x1080 flat panel (which it is). The proprietary driver doesn't do full HD either, but at least I can get it up to 1280. On this machine, I do get periodic freezes, where the mouse pointer still moves around the screen, but clicking or typing have no effect. Only a hard reset/reboot fixes this. Any mention of this immediately gets fingers pointed at the proprietary driver, so I am kind of stuck on this one. I just have to get a newer monitor I guess.
In recent releases some default mode lines stopped being generated, so that just requesting a higher resolution in your xorg.conf file won't work. You also need to define appropriate mode lines as well. You can use cvt (or a couple of other programs) to generate mode lines that won't fry your hardware and add them to your xorg.conf file. I have a couple of monitors that I need to do that with.
For example:
# Xorg configuration created by system-config-display
Section "ServerLayout" Identifier "single head configuration" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" EndSection
Section "InputDevice"
# keyboard added by system-config-display Identifier "Keyboard0" Driver "kbd" Option "XkbModel" "pc105+inet" Option "XkbLayout" "us" EndSection
