The video4linux project feeds the kernel with "snapshots" of its code
as well as severe bugfixes and security issues withing minor kernel
releases.

IOW video4linux kmdls will probably be a couple of month ahead of the
kernel. But the authors are the same.

rpm -e

No, no need to, it is all packaged in a way that rpm -e will rectify
everything (other than rmmod'ing any loaded module).

No rpm should overwrite stuff of other rpms. In fact a depsolver would
choke on that with "file conflicts".

So you're safe to install kmdls, modprobe them, test them, and if you
don't like them, rpm -e & rmmod them.
