Well, the current 2.6.5 powerpc kernel has miboot friendly size, so it
should be ok. We also tried booting the pmac-elf kernel with builtin
initrd on a prismo from the netbooting OF directly, but there was some
error because the compressed kernel + initrd was bigger than 4Mo.

That said, this 2.6.5 kernel use a initrd for module booting.

Did you make progress on 2.6 d-i on ppc ?
