Also important is an OpenFirmware interface because we should migrate
away from x86 real mode interupt system. OpenFirmware would give us a
clean, standard way for boot loaders or OS's to talk to the hardware. It
would give us a configuration interface (albeit not too simple). And we
could include a couple (or one or three) bootloader packages, e.g.
linux_boot, multi_boot, chain_boot.
