It could be done in superio.c where the mask is being set.

That was one of my questions. Aren't these settings mainboard specific? In
that case we want to set them in each mainboard. Otherwise it'll bite lots

If we're going that way, I'd rather just use what we have and change the PNP
code to match. (Let it create dynamic devices but pass more information in
the info structure so that the enables get set, etc.) The hierarchy buys us
nothing if we just make lots of little files and types.
BTW: Does anyone see PNP devices besides the SuperIOs? I.E., will the PNP
code ever get used for anything else?
I think this is closer but maybe still not right. This could be the

Yes. Let's get it right.
