Anybody want to give me a hint? I'd start by copying lpbb, replacing the parallel port code with appropirate gpio calls.

Maybe take a look at NetBSD -current. It has all that you want. It is
a pity FreeBSD did not take theNetBSD GPIO framework, but shoehorned its
own (although they cleary took code and concepts from them).
