   BTW: I wouldn't suggest that anybody try this...
   
   I just looked at NetBSD's SCSI CD-ROM driver, and it looks like it
   doesn't even try to understand anything other than a whole-ROM ISO-9660
   partition.  It doesn't even bother trying to read a native disklabel
   off the drive.  grr.

this doesn't match with my experience.  i've mounted separate
partitions from a sunos cdrom (4.2 ufs format), under netbsd/sparc.
