Well, I know Ethan doesn't like this solution, but I personally like it
and feel it's ok for people who know what they are doing ;)

First, I have no bootstrap partition. I have a (around 1Gb) HFS standard
partition that I use for exchanging things between Linux and MacOS. On
this partition, I have yaboot, yaboot.conf, the kernels (but those could
be on ext2) and the OF boot script.

All I do is to configure OF manually OF to load the script (setenv boot-
device hd:10,script) and that's all.

I also have a fake System and Finder (included). Those are seen by MacOS
9.0.4 on my box as "legal" system & finder and MacOS will not unbless a
fake system folder with them in it. (In fact, it will even re-bless the
folder).
I _know_ that this doesn't work for all combinations of machines. It does
work for me (Pismo). Basically, my setup looks like:

 /Scratch (HFS exchange partition)
   |
   |-/Bootstrap (fake system folder)
       |-Finder (fake Finder)
       |-System (fake System, could be miBoot for oldworld)
       |-MagicBoot (OF boot script with the type/creator of
       |            a MacOS ROM file (tbxi/MACS))
       |-yaboot
       |-yaboot.conf
       |-kernels & ramdisk

Ben.
