the bus-dependent code and to be able to support more systems. The core of the new code is mostly obtained from NetBSD. Kluge the interrupt routing methods of the psycho and apb drivers so that an intline of 0 can be handled for now; real routing is still not possible (all intline registers are preinitialized instead); this will require a sparc64-specific adaption of the driver for generic PCI-PCI bridges with a custom routing method to work right.
