[Soekris] MiniPCI GPS on Net4526

[David Dudley]

War Driving, huh ;-)

We have a number of the net4801's in the field running kizmet and
NetBSD with a gps device that talks over the internal serial port.

The gps's were provided by a contractor, and I've never been able to
get a model number from them that I can cross ref.  Little card says
'powered by SiRF' on it, but I never paid it any mind, it just works.

Units have a Atheros WiFi mini-pci card, and they're always on the
lookout for an AP to attach to.

Our remote units are installed in some of the City maintenance trucks,
and update a MySQL database on my server here through the network when
they can attach to it, showing where they found access points, and
whatever info that kizmet can grab from them.

System works great, and is NetBSD based.

We are planning to connect a few of them to roving Soekris boxes on
vans
to map the AP coverage on our site to get a better idea were coverage
is.
