David,

Actually, if an /etc/xorg.conf exists it will be used. The key will be
an hsync spec in the monitor section that will allow a dot clock
frequency high enough to support 1600x1200 operation.

If you don't have the specs available, you can use the 'gtf' utility to
compute a modeline you can use in your xorg.conf file:

        # gtf 1600 1200 60
