I use MacOS 7.5.3 on everything; even 8 MB systems. The overheads are
small enough since you don't need any system extensions to run Penguin.
You can disable those with the Extensions Manager control panel (I think
that's what it's called) or just restart and hold down shift key when you
hear the chime. A few seconds later you will see something like
"Extensions disabled" on the screen.

Sounds good. I didn't know emile could do that...

Right. I can't validate these files as I have no m68k Mac hardware to
hand. Perhaps Scott or one of the Debian developers can test this initrd
and kernel binary on a Mac.

If you are comfortable with cross compiling kernels, that's the best way
to go. If not, and if you can't use the Debian kernels, then let me know
and I'll build a suitable kernel binary for you.
