Can't get anything better than 800x600 resolution

[RL]

I just got an Nvida PCI GeForce FX card, installed the NVIDIA drivers
correctly (it loads), did an xorgconfig, and made the appropriate
changed in xorg.conf.  I have a "DefaultDepth 24" line and under depth
24 I have Modes "1024 x768" etc...  However, when I load X, it loads
at 800x600 and I can't up its resolution in GNOME nor can I up in on
my keyboard with the numeric +/- keys.
