-}The raw scsi device is only needed by mtx to control the changer.

Urk.  Forgot to mention that I tried this.  I even have the link up yet where
I found to try it:
   http://www.bacula.org/en/dev-manual/Autochanger_Support.html

I didn't use nsa0, but instead used nsa0.0 as the above link suggested, with
the same error:
   root dude ? btape -c /usr/local/etc/bacula-sd.conf /dev/nsa0.0
   Tape block granularity is 1024 bytes.
   btape: butil.c:285 Using device: "/dev/nsa0.0" for writing.

FWIW, /dev contains:
