/usr/X11R6/lib/X11/Cards is marked as documentation file. This is definitely wrong. Rationale: If you want to do a documentation-less installation (excludedocs in RPM macros), the X configuration doesn't start because it depens on the Cards database. You have to reinstall XFree with --includedocs after reboot an start Xconfigurator manually.
this is an Xconfigurator issue.
This is not the case in recent Xconfigurators.
