Your original post (see later in this post) shows that the kernel
recognized your tape drive. Thus you do not need to re-compile the
kernel. Just make your devices with 'mknod'. The 'st' devices have
major 9 and minors 0 - 7 (for st0 -> st7) and the rewind devices
('nst') have major 9 and minors 128 - 135 for nst0 to nst7.
Just make them (as root, see man mknod), ensure the ownership is
root:tape and permissions 660, and add (if necessary) your userid to
the tape group in /etc/group.
As far as I know, you only need /dev/st0 and /dev/nst0. Those are the
only two I use.
