Yeah, it looks like that's what I have to do.  The 405 apparently requires the
OS to configure a number of things (for instance, to guess what MAC address
the ethernet controller has), and this is normally done through information
passed in from openbios or RedBoot.

I've gotten as far as "root device?".  Now to build a kernel with support for
NFS root, and a complete userland for it.  I still have some holes (no clue
what to do with the gpio to get control over the LEDs), but I'm able to bring
the system up and detect attached devices.
