Setup: Ubuntu 7.04, Dell D620, nVidia NVS 110
The only convenient way that I found to correct my resolution problem turned out to be very simple:
edit xorg.conf with output from command gtf, where resolution arguments are manually provided.
$ gtf 1440 900 60
# 1440x900 @ 60.00 Hz (GTF) hsync: 55.92 kHz; pclk: 106.47 MHz
Modeline "1440x900_60.00" 106.47 1440 1520 1672 1904 900 901 904 932 -HSync +Vsync
update monitor section in /etc/X11/xorg.conf

You could also try booting from a live CD and copying the xorg.conf
file, assuming the resolution is correct in the live session.
