Despite several examples in the kernel, the third argument of
sysctl_handle_int is not sizeof the int type you want to export.
The type must always be an int or an unsigned int.

Remove the instances where a sizeof(variable) is passed to stop
people accidently cut and pasting these examples.

In a few places this was sysctl_handle_int was being used on 64 bit
types, which would truncate the value to be exported. In these
cases use sysctl_handle_quad to export them and change the format
to Q so that sysctl(1) can still print them.

Change the embedded module name from "bluetooth" to "ng_bluetooth" to match
the rest of the names assigned to this object.

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)
