I think permissions are the most likely problem; that'd cause mt
to be unable to open the device - many utilities don't
differentiate between being unable to open something and that
something not existing.

Gavin; default Gentoo udev rules set the group of st devices to
'tape' (see /etc/udev/rules.d/50-udev.rules' so add your user id to the
tape group.
