There are so many problems and ambiguites with having non-unique
module names it is not even funny:
- when I modprobe scx200 what willI get?
- if I want to blacklist one of the modules (let's say hotplug) how do
I do that?
- lsmod (with everything else compiled in, possible?) - which one is loadded?

...etc, etc...
