Oh, I didn't mean each sub-chip driver, I meant the "southbridge driver". Right now that's really only the PIRQ table mini-driver (all ten lines of it ;)
Sadly, we do _not_ have a really good generic model for setting interrupt lines. The PIRQ stuff comes closest to a driver model, but it gets disabled by the MP table parsing, and then we don't have anything good to fall back on, I'm afraid.
