rolling up an initrd & kernel is actually very simple; but I had to read
the Makefile to figure out how to do it!  I do it by copying
ramdisk.image.gz into arch/ppc/boot/images and building 'make
zImage.initrd'.

So... how do you build the initramfs?

I'd prefer to use initramfs; I just haven't had a whole lot of luck with
it and other concerns took my focus.  :/

Thanks,
