You are referring to the entropy pool used for /dev/random and
crypto operations ?
You could setup a video capture card or radio tuner card, tune it into
a good noise source, and arrange for the bit stream to get written
to /dev/random
Because anything written to /dev/random gets mixed in / XOR'ed
into the entropy pool
