On FreeBSD 7.3-STABLE I'm mounting a DVD and doing something like

It sounds like what you really want is to load the contents of the
specified file as a memory system? That's not part of mdconfig's
repertoire, to the best of my recollection.
If that's what you want, you need to use a different tool; the purpose
of mdconfig is to provide scratch disk. The backing store is to
specify a region its contents can be swapped out to if the system is
under memory pressure (which certainly won't work with a DVD)
