But modprobe kvm_intel already works.  Just convert any - to _?

Well, you could get kernel developers to rename their files with
underscores.  I've CC'd them.

We use _ because we turn the module names into identifiers; it's also
the most common choice, and having both is just confusing.

It shouldn't break anything to rename them, if there's consensus I'm
happy to create a patch.
