Will try cook up something along those lines. It'll be easy to verify if
the probes inserted and removed properly, but verifying handlers run
correctly will need some work.

We have a sort of regression test bucket that uses expect to parse the
dmesg to verify handlers did run correctly; that isn't a totally
in-kernel solution anyway. I have a couple of ideas in mind to make it
easier.
