When I comment out the HorizSync and VertRefresh lines in xorg.conf
(either the old one or the one modified as above) I end up with 800 X
600 resolution.  gnome-display-properties gives that and 640 X 480 as
the only options while /usr/bin/system-config-display bombs off.

I'll try the livecd and Xorg configure approaches next....
