Thanks for your answers, it sounds very straightforward.
One more question: Currently I'm using the book Linux Device Drivers 3rd
Edition (2005) as a reference, and it's discussing Kernel 2.6.10. Do you
think that's still okay, or should I get/buy a more recent book on this
topic, and which would you recommend?
