As an aside, you sure you want to do this anyway?  I'd suggest that you
just do a gpio chip driver for this, tie it in to gpiolib and use the
gpiolib user interface (which IIRC has only made it as far as -mm but is
on the way up).  This gives kernel internals nice access to the pins as
well through the standard gpio framework.

Thanks :-)
