I do need to look at PPCboot again...  We, presumably, will need to
create an image that PPCboot will understand--unless it understands
straight gzipped ELF images, in which case, this whole part of the
discussion is moot...  ;-)

Unfortunately, I'd rather not assume that everyone's installed ppcboot.

No compression yet.  Yes, the filesystems are stacked (layered is the
more common term) in NetBSD, and if there were a compression piece, you
could presumably put that in there.  The "block translation layer" just
provides access to an array of blocks and you could put any filesystem
you want on it (cd9660, FAT, whatever--ffs is the one I've played with,
though),
