Add support for XBOX to the FreeBSD port. The xbox architecture is

nearly identical to wintel/ia32, with a couple of tweaks.  Since it is
so similar to ia32, it is optionally added to a i386 kernel.  This
port is preliminary, but seems to work well.  Further improvements
will improve the interaction with syscons(4), port Linux nforce driver
and future versions of the xbox.

This supports the 64MB and 128MB boxes.  You'll need the most recent
CVS version of Cromwell (the Linux BIOS for the XBOX) to boot.

Rink will be maintaining this port, and is interested in feedback.
He's setup a website http://xbox-bsd.nl to report the latest
developments.

Any silly mistakes are my fault.
