That seems to be O.K.

Fine! *eg*

Yes sure I am. To my knowledge for now - there are only outb() neccesary
to put data on the GPIOs. And before using the GPIO there has a) to switc=
h
off the "LPC" behaviour of the J2 and to b) set in- or out-direction of
the GPIO pins. All that is done by outb().

I found 2 examples from other WRAP users doing some stuff (switches and
some optocoupled relais):

I found there code is handy for the a) part. And there is no special
kernel issue.
