The second try a committing the bluetooth code

Has been seen to work on several cards and communicating with
several mobile phones to use them as modems etc.

We are still talking with 3com to try get them to allow us to include
the firmware for their pccard in the driver but the driver is here..
In the mean time
it can be downloaded from the 3com website and loaded using the utility
bt3cfw(8) (supplied) (instructions in the man page)

Not yet linked to the build
