You didn't mention what kind of monitor you were using.  Not that this
is necessarily relevant, but if the monitor is Plug-n-Play, the RH X
config tool may be reading that value from the monitor and sticking it
in the XF86Config as a safeguard.

The EDID support in XFree86 (EDID is "Plug-n-Play for monitors",
basically) has been slightly controversial in the past.  In previous
XFree86 4.x versions, the X server itself would read the EDID
information and override some settings in XF86Config, assuming it knew
better than you did about those things.  It's therefore possible that
RH, irritated by such behavior (they aren't the only ones, believe me),
disabled it and moved that code into the XF86Config generator.  That
would explain why the server needs information it never seemed to need
before.

But all that is speculation.  I'm running XFree86 4.2.1 on Debian
sarge/sid with an ATI video card and a Samsung 19" monitor, and I've
never seen that.  If you want to know for sure, grab the source for
kudzu (or whatever it is that does X autodetection on RH) and see for
yourself.
