Thanks for posting. I assume you restarted X and saw not difference.

My only thought is the the ATI driver that FC4 has is not the same as
the ATI driver FC3 had. Your xorg.conf seems ok. You could remove some
of the Modes, just keep the ones you like.

The gnome | kde tool may not show you the max resolution but the system
stars at the max. resolution and then drops to the lesser if the driver
cant handle it.
