I've added support for Intel's hardware random number generator to the
NetBSD-amd64 port in NetBSD-current a few minutes ago(*). I would therefore
be interested in feedback whether this works as expected. To benefit of
this change you need an system using an Intel EM64T capable CPU on an
i9xx chipset based motherboard running NetBSD-amd64.

Using a kernel with my changes the kernel should print the following
message during system startup:

pchb0: random number generator enabled

"rndctl" will tell you whether it is delivering randomness:

tron@lyssa:~#rndctl -ls
Source                 Bits Type      Flags
pchb0               1915488 rng  collect

	Kind regards
