Making it cleaner was exactly the point ;)

Ok, I see.

I don't like the idea to make bttv depend on the dvb core, I think that
will happen when doing it this way?

How the initialization is done?

We'll need both attach and detach I think.  "rmmod $frontend" should
work, even if it is only for small driver development turnaround times.
