Yep, good plan, that's what evbppc does (well, the ibm40x systems) -- single
ext_intr() handles three different interrupt controllers with just a bit of
ifdefage.

Is there any reason why various powerpc ports couldn't just use generic
powerpc bus space/dma backends (arch/powerpc/bus*)?

Not sure I'll be able to make it to the hackathon, though...
