who's holding the stick?
Really.

I've seen some of these case, where the distro kernel has something as
a module, but the other parts of the distro the unconditionally load
that module always. That makes no sense.
If you have 105 different real devices in your system, that have
different drivers, sure, I'll buy 105. Somehow I doubt Rusty's box has
105 ;)
