I'm working on a driver for the ESP board.  Granted this is the first
driver I've written so I'm expecting this to be a painful process.
But I do have some sample source from Hayes and with that in fist,
I've put together something that correctly probes the card's existance
and retrieves the settings.  The next step is to turn on the card
in enhanced mode and ensure the settings stick.  Finally, it'd be
cool to do some i/o ;)

If you've an ESP and are interested in helping write or test this
driver, drop me some mail.
