Right. So this is all item (3) stuff. I agree with you there --
packages need to express the dependencies in whatever way they can.
That might mean printing nice messages if the correct dependency isn't
obvious.

For (1) and (2), though, what do you think of the warning I've added
to Gentoo? That's what I meant by asking for thoughts on "this
pattern" -- the whole thing with comparing running kernel and
compiled-for-kernel and comparing loaded-module-version and
compiled-module-version.
