Excellent idea for a topic - a lightning talk perhaps that someone can present
at ALE-NW on Tuesday?

Google found a few how-tos for drivers quickly.

It would help if you understood C compilation and dependencies. Then all you
need to understand are the normal module loading, unloading, listing and
options.  It is just C code.

Only skimmed the link, seems to cover everything.

Just know that if you go this route, then you'll need to rebuild the module with
every new kernel.
