bttv driver does not expose GPIOs to the userspace but I expect it can be
modified to do so. Have a look at the GPIO_BT8XX driver to see how to do.
Beware that GPIO_BT8XX is thought to drive physically altered boards
(hence not working as brand new product - read the help message of the
driver) while the bttv one has to keep all the other functionalities, so
you may have less GPIO to play with because some are wired to something
on the board itself.
cheers,
Domenico
