I agree with you in principle.  However, my monitor is not that old, it is
Mitsubishi 21" CRT and it is detected just fine when I plug it right into
the computer.  When I run it through the KVM switch, something gets lost and
The monitor is not detected correctly.  If I plug the monitor indirectly, 
boot the machine, and then put the cables back in the KVM, it is fine until
the next reboot.  I have tried various tricks to capture the Xorg.conf file
>From the direct plug in and then put them back.  There were also various
options suggested for FC12 to disable some of the monitor scanning, but
they were ineffective.

My desire now is to find the detected EDID and hardcode it as a kernel parameter as was suggested when the thread first started.

PS. I do appreciate your time Bruno.
