What does it have to do with OpenPIC? It's the 8259 code, if it's changed to
use interrupt acknowledge, that will need this information.

Well, if/when you change the 8259 code to use interrupt acknowledge, you'll
have to provide an interface allowing ports to tell it how to do it. When that
happens I'll make the Adirondack and K2 ports provide this information.
