Tnxs for the suggestion.  I have compared Xorg.0.log vs Xorg.0.log.old. 
In both cases the system has detected I have a CRT monitor.

In the good case, the monitor is detected as a "KDS visual-sensation" 
model, while in the alternate case it does not recognize the monitor and 
thus assumes it is a generic monitor.  This latter result limits the res 
offered to either VGA or SVGA ONLY.

This is NOT a problem with any distro prior to FC6.  If I swap hard 
drives to an FC5 (or FC4), the monitor is always detected correctly and 
the full set of modes are offered.
