That's a good idea.  The area has been left unstructured by NetBSD software.
And beware, please.  The key is to design software interface, aka API.  The
fundamental issues in Linux camp are they are too HW-centric, driven by
specific engineerings.  The consequence is rather littered outcome like as
MTD or what-so-ever their misguided disciplines.  As technology evolves,
such the solution gets messer, by short-sighted bubbling sub-projects.
