I have written a demon for Linux that gathers entropy from timer jitter and pushes it into random(4). There is working code and a PDF rationale document.
Comment and criticism solicited.

Do not use any version earlier than today's. I just found and fixed and simple but nasty bug. Dumb, much? To combine two 16-bit items into one 32-bit word, I used: x = (a<<16)& b ; because of the AND, that always gives zero. Of course it has to be an OR.
