Yes, firstly, ide-scsi is not compiled in to any production kernel (don't
know about lenny, I use etch; try modprobe ide-scsi to be certain), because
it has been deprecated (see bug #467291). Therefore hdd=ide-scsi has no
effect. The tape drive would appear as /dev/st0 with ide-scsi.

Secondly, ide-tape, which should replace ide-scsi, is broken. Apart from the
bug #327355, it doesn't return some flags correctly; in particular
GMT_ONLINE is always false. I guess this is causing your error.

The solution I adopted, while arguing with the kernel maintainers, is to
build a kernel without IDE-TAPE, and with IDE-SCSI (if you leave IDE-TAPE
in, you need the hdd=ide-scsi line in your startup parameters, otherwise
ide-tape gets preference).

It's a mess...
