It turns out my (2 year old) AMD Phenom 9350e Quad-Core doesn't seem to have that module loaded. In fact, googling for "AMD hardware random number generator" got me a few hits of folks running an ms-windows tool on similar processors and one of the flags checked was for the hardware rng, which always seemed to be "not supported". I guess the modern CPU really don't have that hardware any more. How strange (and sad!). -wolfgang -- Wolfgang S.
