RedBoot is very portable and not at all i386 specific. I just ported it
to the LASAT
boards I support in the linux kernel - it took a few days. When you have
ported it
you almost instantly have a really nice embedded operating system too.
Perhaps
you were confusing it with GRUB?
How this helps with ramdisks I don't know :-).
