Catalyst doesn't use anything. You are specifying mkxf86config in your spec, and 
it's getting run automatically by autoconfig (part of livecd-tools). You are 
free to use something else.

Do you have a patch?

If you're building this CD for a specific computer, use livecd/root_overlay to 
put a custom pre-made xorg.conf on the CD and remove mkxf86config from the 
package list. This will "solve" your problem.
