I reinstalled the everything and, after successfully booting
into a 
fresh system, mounted /dev/sd0a and changing /etc/rc.conf 
appropriately.  I then ran fsck_ffs -c2 /dev/rsd0a.  Got the
message... 
  BAD SUPER BLOCK:  CAN'T FIND SUPERBLOCK and a core dump.

The sysinst installation method is not available to me as I
don't have 
a CD-ROM drive for my old Powerbook 180 and have to install
from files 
located on the Mac partition.  If the traditional method no
longer 
works, it will leave a lot of older machines like mine in
the dust.  So 
much for "Of course it runs NetBSD".

Well, you can always boot the installation kernel, have it
set up the
NetBSD partition(s), then do the actual installation from
the MacOS
installer.
