Have you tried simply removing the Horiz and Vert rates?  The X in Gutsy
does a fair job of guessing these automatically if they're missing.

You can also try installing the xresprobe package and then run ddcprobe
to see what details can be retrieved about your monitor.  read-edid (and
the command `get-edid | parse-edid` is another option; it gives
basically the same info.
