I think the right thing to do is use the ofppc port to probe the tree, and then
write real interrupt handling code into ofppc.  Having done the interrupt code
for a similar port (prep) I can say it's probably not nearly as hard as it
sounds.

Now.. that assumes the interrupt mappings on these machines are sane, and OFW
tells us enough about the machine to set it up and whatnot.  If the machine
uses an OpenPIC or an i8259 for interrupts, it shouldn't be too hard.
