Yeah ok, so it picks ide devices first and then scsi.  But when
you have a ide-scsi emulation that gets to be host1 and so gets
to be after the scsi sr1 drive in the enumeration list of cdroms.

Would be nice to be able to 'check' for media pressens and the types
supported perhaps... as we do in that dvd_test app, then one could know
that it wasn't a DVD drive and/or that it has no media in it.
