One added note regarding this procedure. It might be wise to do an
rpm -qa |grep xorg
To see which rpms that are currently installed on the system. The reason 
is that the U means that any package installed or not will be 
upgraded/installed. The F (freshen) option did not seem to work for me 
when trying to downgrade with --oldpackage option to rpm.

The procedure worked for several that tried this to downgrade xorg-x11 
packages when a major failure hit us on testing FC3 to be.

It is safer than removing x packages via rpm -e and does not remove your 
desktop managers like yum erase xorg-x11 would do.
