I don't know how Virtualbox works, but perhaps some version
in the past installed via rpm and then helpfully compiled
modules for updated kernels and installed those directly --
as opposed to how akmods work by generating a kmod package
and installing that?

But much better than rpm removing directories that are not
empty and contain files which are not part of any package,
of couse. :)

I'm not aware of any such options. That would have to be
done in rpm, I believe. And then it would likely warn far
more often than you'd want.
You could write a quick script which looked for orphaned
files under /lib/modules (and optionally cleaned them up)
fairly easily.
You do have to be careful to not remove some files generated
by depmod (which kmod packages call in their
%post scriptlets, at least).
Running something like this occasionally should help locate
any cruft:
find /lib/modules/ ! -name 'modules.*' -print0 | \
xargs -r0 rpm -qf | awk '/is not owned/ {print $2}'
That's not perfect by any means. The awk portion is
particularly broken if the listed files contain spaces. I
don't know of a way to have rpm output only the filename or
use a different separator.
If I was going to really use such a script I'd look at the
python rpm bindings most likely.
Short of that, I'd tighten the unowned filename extraction
in one way or another. Matching the full line and stripping
out the leading 'file ' and trailing 'is not owned by any
package' is probably the simplest method -- not necessarily
done with awk. It could be grep piped to sed, perl, or
whatever suits your tastes.
