Right, PCI IRQs are terminally broken already. This patch without the
OpenBIOS change won't hurt. With the OpenBIOS change, things start
working better :-)

I appologize for being basically MIA these days, way too busy with
other things. Feel free to pick up ownership of my patches if you
want to get them into upstreamable state, such as the SunGEM one.

I don't know if I'll have any bandwidth to work on that stuff again
until later next year.

Cheers,
Ben.
