That was _long_ ago. bttv uses external i2c modules. There are plenty
of them for various external chips, and I'm working on putting these into
a single module because they have alot of common code.
Currently bttv simply passes down some v4l ioctls to the command function
of the i2c chip driver, and if the driver feels it should care it can.

bttv has minimal support for it (not separate module yet, but I'm
working on it).

bttv module available.

not supported (yet?).
