I have recently started to port/develop a little digital I/O driver for
the Icecube for a Linux driver training course. It allows to configure
some port pins for output and input with interrupts and with a few
jumper cables you can toggle the pins and trigger interrupts. It's still
in a preliminary state. Nevertheless I could send it to you in a private
mail in case you are interested.
