Hmmm, then x11-common Pre-Depends: xfree86-common to make sure that
xfree86-common.postinst is run before x11-common is configured,
shouldn't it? Or maybe remove the conffile in xfree86-common.preinst?

Hmmm again, the Replaces does exist, but if the file is not removed,
conflict still happens. Anyway if someone has time to investigate,
test and provide a patch, that would be very welcome.
