A bit more research shows there must be something loaded into this 
partition to handle the boot.  System Disk defined the following for 
MacOS X:

# ATA Bus 1, ID 0, partition 14
boot-device /pci@80000000/pci-bridge@d/pci-ata@1/ata-4@0/@0:12,\\:tbxi
boot-file 
boot-args 
boot-command mac-boot

Where Partition 14 is the MacOS X UFS partition and partition 12, pointed 
to in the boot-device line, is the MOSX_OF3_Booter partition.

When System Disk is called on to revert to MacOS 9 it defines the 
following:

# ATA Bus 1, ID 0, partition 11
# vRefNum -1, dirID 32664, Classic
boot-device /pci@80000000/pci-bridge@d/pci-ata@1/ata-4@0/@0:11,\\:tbxi
boot-file 
boot-args 
boot-command mac-boot

In this case the boot-device points to the MacOS HFS partition just like 
the comment indicates.

This leads me to believe that the original proposal I made a few months 
ago about building the NetBSD CD for macppc similar to the way the CD is 
built for Sun might work.
