Hey, I'll butt in even though you are correct ;-).
This says to load bttv and it's prerequsites when you access
any device with major number 81, usually /dev/video*
However, if you have more than one v4l device and they use
different drivers, only the videodev module is common and
the other modules are specific to the minor number:
alias char-major-81 videodev
alias char-major-81-0 km_drv # ATI All-in-Wonder
alias char-major-81-1 bttv # WinTV GO
If you only have bttv cards, major-81 is bttv and will work
even though it isn't strictly correct.
