If we're doing an A6, could we perhaps also bring a few currently
unused GPIOs out on test points ? (Somewhere under the LCM.)
Andy made a very good point that we should have access to GPIOs,
and that would be a low-risk way to do it.

I would limit the number to what our layout people are comfortable
with. I.e., what can be done without big changes.
