I wonder if this applies to head.S also? I don't have a manual handy, but since the Alignment exceptions are identical, I guess that DAR & DSISR are also set for the CPUs that uses head.S? Currently only 8xx uses these in the machine check exception, but I think the these registers should be accurate. They may be useful for debugging if nothing else.
