I've always thought it would be neat to do:

        cat bzImage initrd.tar.gz > vmlinuz
        rdev --i-have-a-tarball-piggyback vmlinuz

Linking into the image is easy for hackers, but why not make it
scriptable and super-easy for end users? x86 already has the rdev
utility to mark a kernel image as having certain flags. It could even
be a command line option, "inittgz" or somesuch, telling us that a
gzip-format tarball immediately follows the end of our ELF image.

I wonder if any bootloader mods would be needed at all to do this...
AFAICS you just need to make sure the kernel doesn't trample the
piggyback'd data.
