Uhm, not quite 100% true. Odds are it will use the btusb driver, which 
in turn depends on bluetooth, btrtl, btintel and btbcm which will, in
their turn, load up various firmware files and such.

Not necessarily. Many laptops have the bluetooth built in, but it is
internally tied to the USB system (visible in a "lsusb -v").

In fact, come to think of it, I don't know that I've ever seen a
built-in bluetooth connected to the PCI bus. But that's just me. I'm not
saying it's never been done, but I've not seen it.
