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
