I understood that from the very beginning. 

So... what is FreeBSD doing wrong here? Or what bug did we find in
the firmware? The Linux chrp bootloader gets the memory map
properties okay.

Where's the code for this so I can show it to the guy who can 
instantly say "this is wrong" or "uhh I forgot to code that
property!" :)

Okay I have access to one now (thanks Peter Czanik :)

How do I get a PPC compiler onto there or does every FreeBSD ship with
one now it's a real release platform?

This won't destroy any compiles or objects he made will it? I mean it's
not supposed to but it WON'T, right? :D
