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
some tasks better than others?
