You may not need the monitor section. If anything like DDC (I think
that's what it's acronym is - Display Data Control?) is in operation, it
will piuck up the proper rates automatically. I don't have a monitor
section at all in my xorg.conf. But I'm running a normal "desktop" node
with conventional monitor.

Regardless, even if needed, try what I show below.

My "Screen" section looks like this. Watch out for the line wrap on
"Modes".

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "1600x1200" "1280x1024" "1024x768" "800x600"
"640x480" "1280x960" "1280x800" "1152x864" "1152x768"
        EndSubSection
EndSection
