* KNOWN BUG: If your gbufsize causes a frame to cross a page boundary,
you lose. The code doesn't support this, and doesn't check for it
either. Boom. (this is fixable though)
* Totally untested. I don't own any bttv hardware.

Ok, much better. devfs wants "void *ops" not a struct file_operations.
Attached is a better patch, against 2.4.0-test10-pre7, which allows

power to do whatever they wish.

register multiple v4l intefaces?
The spec seems to assume that people will switch between channels, not
view them all at once.
