    According to menuconfig, it looks like Linux supports hardware RNGs from
    AMD, Intel, and Via. Via at least has published a cryptanalysis of
    theirs: http://www.via.com.tw/en/viac3/via_c3_padlock_evaluation.pdf.

    I am not a crypto expert so I can't comment much more. Also I have one
    of the older C3s without this feature so it's beside the point.
