Okay, we've got consensus on that.  Good.

Yeah, one might think so!  It doesn't, though.  Here's all I get:

  Vendor: QUANTUM   Model: DLT8000           Rev: 010F
  Type:   Sequential-Access                  ANSI SCSI revision: 02

I guess the kernel is taunting me by telling me it sees the drive but it
won't let me use it.

   # mt -t /dev/st0 status
   /dev/st0: No such device
   # ls -l /dev/st0
   crw-rw----    1 root     disk       9,   0 Sep 18 10:31 /dev/st0
   #

So it's there.  It should control this device then, right?  Now, the drive
is really an HP SureStore DLT-80.  From what I can tell from the info I can
find online, though, the Quantum DLT8000 has the same specs as this HP
drive, so presumably there's no problem there -- right?

Here's the entire dmesg output in case someone sees something I don't.  
(Yes, it starts in mid-sentence.  I guess the size of /var/log/dmesg is
limited?)
