[PlanetCCRMA] New xorg plus ATI resolution problem

I've just updated to the latest xorg(6.8.2) for FC3 from the repository.
I am running 2.6.10-2.1.ll.rhfc3.ccrma kernel. The updates went
smoothly, so I thought I would take a risk and install the latest ATI
drivers (actually for 6.8.16).

The drivers work, that is the kernel module compiles and loads
correctly, and DRI/3D performance works fine. The problem I have is that
I can't go beyond a resolution of 1024x768. My laptop uses 1280x800, so
the lower res looks poor.

Has anyone else experienced this, or similar, or have any suggestions?
Otherwise, take this as a warning!
