AFAIK OFW provides interrupt mapping information via the properties of device nodes. But there is no generic interrupt interface. (E.g. OFW calls OS back if a device has signaled an interrupt or the like.) That is why port ofppc runs so slow. All OFW device drivers use polling.
Hmmm... I thought there was a proposal to allow setting interrupt callbacks, but I've been searching for it without success. So probably it doesn't exist :-)
