I agree that %v sounds useful in general. I'm not sure I like it for
this purpose though, as ideally modules.devname (and the location of
/lib/modules for that matter) should eventually become entirely
internal to kmod.

I'll post a patch to the kmod ML to gather some feedback on just
turning kmod static-nodes into a noop when no kernel is found.
