Note that most Windows CE phones are supported by this driver.

# It would be nice if we had a good way to generate this list from the driver
# list itself, since there's now over 400 listed Ids.

Update uipaq for FreeBSD's driver:
o List all devices FreeBSD supports (more on the way)
o Sort the list of supported devices
o Note this was introduced with FreeBSD 7.0
o Include the FreeBSD configuration synopsis
o Bump the man page date
o Put $FreeBSD$ where all the other usb man pages have it.
And add to build.

Bring in verbatim copy of NetBSD's uipaq.4 man page. This in turn was
copied from OpenBSD. I'll adjust the history section to reflect
FreeBSD's history, and attach it to the build later.
