Well, my suggestion is NOT to use such strange configuration and put 
memory at 0, you'll save yourself a lot of time.

Theoretically, it should be possible to make Linux work when RAM 
isn't at 0 address, but you have to fix many places and this requires 
quite deep understanding of Linux and PPC 44x memory management, and, 
frankly, you're on your own in this quest :).
