What level of support does kerneld have when loading or saving values?
Is it possible to have a "boot / initial run" value, and then as the
module gets "tweaked" through the course of the system run time, the
"tweaked" values will be read in from something like a /proc entry that
kerneld will keep for all modules (even after they are unloaded)?

I have not hacked on kerneld, nor even looked at the code so this is just
a "feeler" for others to think about. I might get ambitious and work on
it later but I don't use modules much myself.
