In addition to what Bruce mentions below you might also try (as root) 
running Xconfigurator from the command line.
Sometimes the default X setup dosn't get it right and the screen just is 
unbearable to look at.
I have had that happen, and when I ran the configurator and allowed it 
to autodetect the devices and select everything automatically (except 
the default screen resolution) it fixed the problems.

There have been many improvements in X and in the video drivers with the 
advancements since RH 7.0 came out. It might also be helpful if you 
upgraded to the latest release.
