I changed it while adapting the APUS irq code to the generic ppc irq code,
but I don't really remember what caused that change.
Anyway, that code works with an A4000, so there must be another problem,
that just never triggered before, my guess is a timing problem.

It's better to find the real problem, that code is bascially already in
2.5. Two things which could be tried:
1. Add this call to the acknowledge routine before enabling interrupts:
	hwif->hw.ack_intr(hwif);
2. Move reenabling of interrupts after the request_irq() call.

The first solution hopefullly works, since the second one would be an ugly
hack.
