Look at the nexus driver for i386. That is where bus_setup_intr and
bus_teardown_intr() finally end up ending. They end up calling the
inthand_add() and inthand_remove() functions. Slow interrupts are threaded
interrupts (run in an ithread), fast interrupts are non-threaded (and thus
synchronous) and are used for clock and sio interrupts.
