This should be a new world though, so my above comments probably will not be
usefull though :/

Indeed. Floppy booting is not supported on powerpc except in the oldworld and
perhaps prep case. You would have to extract the kernel from the miboot floppy
image though, maybe i should do so or something. The above kernels should fit
just well on a LS/120 floppy though. You would only need the initrd.gz, the
vmlinux and the yaboot.conf, and probably install yaboot on it or something.
