Please let me > reassure you that RTS is acting on advice of counsel. It's nice to hear from legal counsel on this matter. I don't think that the *usage* of the kernel APIs is the biggest issue here. There are many examples where proprietary code uses these APIs and is not violating the GPL. As I see it, one of the main concerns is because the proprietary and in-kernel target systems are, from what I understand, quite similar, there is the possibility that GPL licensed contributions to the in-kernel target code may have "leaked" into to the proprietary code. That said, proving this is a very difficult problem, but the question must still be asked: Can Rising Tide Systems assure us that there is no GPL licensed code within their proprietary target code?
