Unfortunately, our harddisk.device person made the same mistake, and
we've got one monolithic device as well.  If/when it gets rewritten
we plan to do something more like you're planning.  I think that's the
right way to go also.

(The only thing SCSI specific our driver does it it supports
 sending a SCSI command...ie you can send an arbitrary SCSI command
  block;  it was a last minute thing, and is horrible, and all that,
  but at least means that you *can* use a SCSI tape backup device.
