Hey, just for you to know, the aticonfig tool is broken. It never displays clock for me if more than one card is present.

Ummm... no, I really believe it's some user error on your part.
You REALLY want to supplement the
aticonfig --initial --adapter=all command with the
-f flag, otherwise aticonfig will only modify your current xorg.conf if it appears broken.
Naturally, adequate (root) privileges are required to modify the file.
