ofcourse it's straightforward. Believe me its not really difficult to write low level drivers in linux. You should be more comfortable with the

hardware to write low level stuff. Beauty of linux is the framework it provides to make to it so easy !

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?
