I had problems with dual head configuration, but only attached comments 
to a bugzilla entry.

I have a different (older) ATI card and nothing is displayed on it when 
used as a secondary card. (815 internal as primary).
Going the other way and using the ATI as primary and the 815 as 
secondary cause overlapping I/O for the two graphics controllers. It is 
a real mess.

Anyway, here is a bugzilla entry that another person entered.

I believe that with removing the xorg.conf file, then running 
s-c-display, I was able to get dual head xorg.conf files, though they 
were not setup to my desires. Your problem sounds a bit different 
though. Removing the xorg.conf fle should have at least allowed you to 
create a new file.

The bug that I experienced is below:

I hope an upgrade is made soon for this problem. A bug report for the 
ill behaviour that you are seeing might be good to submit for FC3.
