The new network driver fec_mpc52xx will not work on efika because the
firmware does not provide all required properties.
http://www.powerdeveloper.org/asset/by-id/46 has a Forth script to
create more properties. But only the phy stuff is required to get a
working network.
This should go into the kernel because its appearently
impossible to boot the script via tftp and then load the real boot
binary (yaboot or zimage).
