Not exactly. The 'v4l' in your XF86Config loads the XFree86 v4l/Xv module.
This module will provide an Xv-implementation of the v4l overlay via X.
this is a fancy way of doing very simple display of video on-screen
without needing a lot of code. However, your *kernel* needs to *support*
your card before X can *use* the card, so you load both the v4l modules
(videodev.o, v4l2-common.o, etc.) and the driver module (e.g. zr36067.o or
zoran.o, depending on whether you use the CVS driver or the 2.6.x
built-in one). Then, your kernel supports your card and X can use it.

Hope this makes things clear,

Ronald
