Linux Device Driver Kit
This is one for all the linux hackers out there, and you know which type I mean. If you can code, and have a piece of hardware that linux doesn't support, why not make yourself a driver for it? http://lkml.org/lkml/2006/5/24/238 has more details on the kit. Come to think of it, I can code, so I might start making Linux drivers soon. You never know.
