Note that you really should talk to your lawyers about this; it's not entirely clear if such non-GPL kernel components are legal or not (personally I don't think they are). For example, see the statements from Linus Torvalds on this at http://people.redhat.com/arjanv/COPYING.modules . I also wonder if the *driver* or the hardware has the "valuable IP" that needs to be protected, most of the time it's the hardware after all. Even if your lawyers think you're in the clear, it's a major pain. Well that's actually an encouragement to make driver vendors consider if the IP they try to protect really is worth the hassle... because a hassle it is. ABI and API change with every kernel release. And lots of people run *lots* of different kernels, including kernels with really weird patchkits.
