True. One of the directions would be looking at NetBSD code, as they have some
ppc405 support (at least Walnut platform was supposed to run when I last
looked it it).

Yes, and getting the loader to work should be a pretty easy step: our existing
PowerPC loader(8) for U-Boot should run as is in most cases: it's known to
work on MPC85xx (e500) and MPC83xx (e300) and I don't see why this code would
not run on other PowerPC variations.
