Some time ago, I have seen something that could resolve your problem. It worked in a ppc750 (and not with a linux kernel) but the idea was that, in the boot process, the memory was not ''cleaned'' and just a few bytes were corrupted (the first 8 bytes in every 64k, I suppose...). So, the ideia is to store the data in the memory that was not corrupted. Don't know if this works in other ppc versions...
