Well, it beats my "reverse biased 2N3904 with amplifier" RNG in terms of
coolness factor	, but my '3904 RNG will probably generate more random numbers
per second. Feed them into a bias-filter (if TWOBITS = 11 or TWOBITS = 00
then DISCARD, else TAKE HIGH BIT), then a SHA-1 hash. Collect a few hashes
and make an RSA key with them :)

Later.
