Does the machine name in the root of your device tree match the name
the code in arch/powerpc/platforms/52xx/whatever.c? You get what you
are seeing if the names don't match.
You also get this error if the kernel is looking someplace where the
device tree isn't.
Do these need to match? 007fc000 and 00800000
