Keep in mind that I'm ignorant.
You had mentioned earlier that it not only changed resolution, but
revereted to analog monitor. I don't know if this will help, but have
you run kudzu? Check /etc/sysconfig/hwconf. /VIDEO/
You should see your new monitor in there. I don't know enough to know if
this has an effect though. I presume that when X terminates, the driver
is unloaded. When it starts up again, the driver would be reloaded. I
don't know if DDC gets involved here or not.
Check your X logs (/var/log/X.[0-9].log for messages.
