It's probably best to avoid all of this upfront. It is pretty easy to load a non-GPL module into a distro-built kernel and call GPL-only functions. (And without doing horrid things with kallsyms.) As soon as you actually need to do one, adding others isn't a problem. David - Registered Address Lakeside, Bramley Road, Mount Farm, Milton Keynes, MK1 1PT, UK Registration No: 1397386 (Wales)
