Apparently not.  There is a Linux support site:  From the site, it appears that one person has
created a userspace driver using the Linux SCSI generic driver, and that
the native driver "osst" is officially part of the kernel source.
Therefore, I would suspect that the information to make this device
NetBSD-supported is out there.

... ah, after looking at the Linux kernel configuration help, here is what
they have to say:

OnStream SC-x0 SCSI tape support
  The OnStream SC-x0 SCSI tape drives can not be driven by the standard st
  driver, but instead need this special osst driver and use the  /dev/osstX
  char device nodes (major 206).  Via usb-storage and ide-scsi, you may be
  able to drive the USB-x0 and DI-x0 drives as well.  Note that there is
  also a second generation of OnStream tape drives (ADR-x0) that supports
  the standard SCSI-2 commands for tapes (QIC-157) and can be driven by the
  standard driver st.  For more information, you may have a look at the
  SCSI-HOWTO <>  and
  <file:drivers/scsi/README.osst>  in the kernel source.  More info on the
  OnStream driver may be found on <> Please
  also have a look at the standard st docu, as most of it applies to osst
  as well.
