freebsd-dev/sys/isa/syscons.c
Doug Rabson 08b6a4cbee * Add hooks to allow the X server to access I/O ports and memory. 
* 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.
