SuSE 8.0 should be using X4.1 or 4.2, which means that the configuration
file it will parse _first_ is XF86Config-4. So, first things first, check
and see whether or not there is an XF86Config-4 file. If there is, that
is the one that your X server will most likely be using. IF that file
isn't found, then it will parse XF86Config.
With some distros the order is userdir/XF86Config-4, userdir/XF86Config,
/etc/X11/XF86Config-4, /etc/X11/XF86Config, so check all of those paths.
This file could have different options than the file you listed below, and
may be the reason you have a lower refresh rate.
Next, you should look at the output of /var/log/X.something.log. This
file will tell you why (or at least give hints) as to why X is limiting
the display resolution.
After checking the log file and the config-4 file, hopefully some things
will resolve themselves.
