* Update drivers to the latest version of the bus interface. The ISA drivers' use of the new resource api is minimal. Garrett has some much cleaner drivers which should be more easily shared between i386 and alpha. This has only been tested on cia based machines. It should work on lca and apecs but I might have broken something.
