As I said, urandom driver details change, but last I looked the Intel RNG is only Xor-ed into the urandom driver's output. It can't hurt--even if the NSA knows every bit it ever outputs--and it might help (maybe the NSA slips some in tracking your RNG hardware's state). But it won't help you with your entropy accounting, it is not credited to the pool. Actually, I think the detail of how they use Intel's RNG changed, but it isn't being trusted. It is only a can't-hurt extra in the mix. (When the Snowden stuff came down, Ted T'so, the original and recent urandom guy, was very relieved that, despite pressure, he didn't accept Intel's RNG output on faith.) -kb
