BayStack 650 driver for FreeBSD3.3+PAO

[Atsushi Onoe <onoe at sm.sony.co.jp>]

I've just ported Bill Sommerfeld's NetBSD driver ('awi') for BayStack 650
to FreeBSD 3.3+PAO.
Though it is just very alpha port not to be released (in particular
name and directory of source files must be changed), it might be
helpful for FreeBSD notebook users.

ftp://onoe2.sm.sony.co.jp/pub/awi-991109a.tar.gz

you have to add .c files to "files.i386" and put "device awi0"
line into your config file.
and, add contents of "pccard.conf.add" file to /etc/pccard.conf

Restrictions
	file name must be changed to solve conflict with ux driver.
	only works with PAO
	much more should comes here...
