Ah, it's even simpler. :)

Try the `mt comp 1' command.  I've just checked, it's around there at
least since FreeBSD 2.0.5.  The man page still lies that it were not
implemented though... but i cannot remember a single feedback whether
it's actually working now.  It has been implemented blindly after the
SCSI-2 specs by Julian Elischer.
