I have a "system" for setting the GPIO pins to the desired input/output mode from user-mode code and then controlling them pretty much like a parallel port. The old Debian system you built at Stuart's place about 5 years ago finally stopped working on the latest Beagle version, and I had to work through Robert Nelson's fine instructions to customize a kernel from a set of files he has online. I have no idea whether things will be as simple on the Pi or if any of the things I have learned about interfacing would transfer to it. I'm pretty sure I could transfer what I have working on the Beagle to the Bone with relatively little trouble. And, the new Bone Black is only $10 more, for a lot more I/O functionality than the Pi B.
