why can't userspace talk to this external hardware and get a count from
it, and then insert it into the random pool without involving any kernel
module?
also, anything that depends on the exact CPU clock tick of when interrupts
happen has just sacraficed a LOT of it's randomness to the particulars of
various motherboards.
