Intel's new secure EPROM has a supposedly good hardware source of random
numbers built in.  I don't think you can get at them yourself though,
it generates one, encrypts it, and sends it out to be sure you really
know the decoding key.

I think it's based on random thermal variations but don't remember exactly
how.
