OF 3 needs a partition of type Apple_Boot in order to be able to load
ofwboot.xcf from the disk. And all that partition needs to contain is
ofwboot.xcf. You'll need to use pdisk to repartition the disk, and make
it so that partition 2 is Apple_Boot (making it the default 800kB is
sufficient). The rest of the disk can be divided into various NetBSD
partitions. More detail is in the install notes in the sections
covering OF 3.

If you're not interested in mucking about with jumping from system
to system, you can set this up with your netbooted NetBSD system.
Install hfstools on your netbooted system, and use hformat to format
the Apple_Boot partition and hcopy to copy ofwboot.xcf onto it. After
you've done that and set up your NetBSD partitions (including
installation), the boot command will be as the examples in the OF 3
section, probably something like:
boot hd:2,\ofwboot.xcf hd:3,/netbsd

Be aware that under OpenFirmware 3, NetBSD is picky about partition types,
and use the types listed in the install notes. In pdisk, the NetBSD
partitions need to show up as type Apple_UNIX_SVR2 (for both mountable
partitions and swap).
