PPCBoot passes the MAC address as part of the bd_info structure. The
Linux kernel must pick it up there. Either you missed to adapt the
kernel header files so that your Linux kernel does not use the same
layout of bd_info as used by PPCBoot, or your kernel sources miss the
part that extracts the MAC address from the bd_info struct.
