As I said, when I used the ATI FirePro 2460, there was NO xorg.conf
created or required. I would have needed one for the ATI 2450 or the
NVidia NVS 420, but I never tried to create one.

I suggest that you restart the machine without X (in run level 3), then as
root
do:
# X -configure
which will write a new xorg.conf.new in the current directory.
But are you sure the problem is in the xorg.conf? What does System ->
Preferences -> Display show?
