Thank you very much for your kind explanation! Now, I understand the
situation. Yes, it should be better to keep kernel ABI compatibility
b/w the three powerpc architectures.

At the moment, unfortunately, something is still missing; nfs module,
e.g., compiled for oea causes kernel panic on ibm4xx. But it should
be worth trying to fix it!

Thanks,
