Pull up revision 1.4 (requested by wrstuden):
Add support for reading MacOS-partitioned disks. Stolen from the mac68k
port, but modified in that macppc searches for netbsd-partitioned
disks before MacOS partitioned disks, since installboot generates a
fake MacOS partition table which isn't the one we want to use.
