* 1280x1024 resolution (I know this'll work)
* 20 Khz to 50 Khz Multiscan frequencies (this is where the hangup is...)

Ok, the manual says 60 to 75 Hz refresh, but that would only apply if the
above were a typo... I've got my monitor right now set up at a
VertRefresh of 50-90 and it works fine...(20-50 seems awfully low for
refresh anyhow...<g>) But if that really is HorizSync, will it work? My

Aren't you confusing the refresh rate (vertical sync rate), which is
usually in the 30-100 Hz range, and the horizontal sync rate, which is
roughly equal to refresh rate divided by the number of lines on your
display (typically in the 30-60 kHz (KILO Hertz) range)?

For details on dot clock/hsync/vsync see Eric Raymond's writeup, often found in
/usr/X11R6/lib/X11/doc/VideoModes.doc
