Claiming the NSA colluded with intel to backdoor RdRand is also to

I think you take this more than a little too far. I see CPU-integral
RNGs as very valuable source to b

How badly patent-entangled is Intel's RNG? Can the fundamental
principle be extracted into an open design?

needs of the NSA well.
It's SP800-90A, B & C (but B & C are draft).
