Hrm.. the faulting address is outside of the zImage. Odd. Can you try loading a plain vmlinux instead ? (feel free to strip it). yaboot 1.3.13 might not be the best one to load a real ELF ... On my side I'll dig one of my old powerbooks and see if I can reproduce (I generally tend to netboot the zImage directly, but it needs to be < 4M for that to work due to Apple OF limitations, or use yaboot with plan vmlinux which exercises a different code path within yaboot).
