* 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.
* Support for AlphaStation 200, 250, 255, 400
* Untested support for UDB, Multia, AXPpci33 (Noname)
* Support for Personal Workstation 433a/433au, 500a/500au, 600a/600au (Miata)
* Some minor fixes and improvements to interrupt handling.
