- Move initialization of the ISA bus from typhoon_init() to clipper_init(); this apsect of device topology is really associated with the individual model, not the core logic chipset. typhoon_init() now returns the IRQ to use for the output of the ISA PIC. - In clipper_init(), instantiate an i82378 instance, and connect its PIC output to the ISA IRQ input provided by typhoon_init(). Remove the explicit instantiations of i8254 and i82374, as these devices are subsumed by the i82378.
