Yeah...my first guess would be that you have a NetBSD disk label on
that disk instead of a SunOS-compatible disklabel.  (Of course,
strictly, what you need is not compatability with SunOS but rather
compatability with Sun ROMs, but for our purposes they are the same
thing.)

A while ago, I tossed out a program "sunlabel" here (and port-sun3),
that lets you do Sun-style disklabels directly on the disk.  It doesn't
work "live"; you have to reboot after changing the label.  (Or, if it's
a removable drive, eject and reinsert the media - incidentally, it'd be
nice of there were an ioctl analog to that for fixed drives.)  If you
have trouble finding it, I'll be glad to mail it to you.
