That's probably a bug in the configuration file generated by Xorg and,
quite possibly, a bug in the Handbook section.  Most modern monitors and
video adapters work without any HorizSync or VertRefresh line in
`xorg.conf'.  This forces the X11 servers to query the hardware for the
supported refresh ranges, and I've found that it tends to be much easier
to get things right this way :)

I'm using an ATI on the laptop used to type this message.  The file
/var/log/Xorg.0.log lists it as:

    ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]

The `xorg.conf' file has commented out entries for HorizSync and
VertRefresh, but this doesn't keep things from working.

    Section "Monitor"
        Identifier   "Monitor0"

        # Uncomment if you don't want to default to DDC:
        #HorizSync    31.5 - 79.0
        #VertRefresh  50.0 - 70.0

You may find it easier to comment out these lines from xorg.conf, start
X11 and then tune the best refresh ranges later, after you get things
working fine :)
