I gather it's either a normal part of the Xorg or kernel installation.
But seeing as the man file for it comes with X, I think it's mostly X
related.

You could see if you have some of the same files as I have, noting that
xine and vlc are players I've added after I already had things working
that used v4l (e.g. gnomemeeting).  I'd guess that if you've got
something installed that uses it, like gnomemeeting, it'd be included as
part of the dependencies.

$ locate v4l

NB: $ is my prompt, what comes after it on the same line is what I've

I would have thought that if it was supported by video4linux, you didn't
need to do anything more.  I didn't have to with a rather crummy webcam
that I tested on my box.
