anything about generating random numbers. Am I missing something so
obvious if it was a snake it would have bitten me by now?

I have to generate quite a few random keys (and iv's) during a days. It
comes out to about 1 million keys (16 bytes each) and 1 million iv's (16
bytes each).
I tried using /dev/random and /dev/urandom but in one case
I can't add anything beyond what is available on a AMD or Intel
motherboard. So is there a built-in HRNG that I can get to (if so, where
is the driver for it)?
Thanks again,

Use /dev/urandom to seed your own PRNG. Or use it to seed OpenSSL's
PRNG.
Why are you asking on this list anyway?
Generating one or two random numbers over a period of time isn't a big
deal. Generating 100,000+ 128 bit random numbers an hour taxes
/dev/random and /dev/urandom. Even the use of EGAD doesn't help.
If you re-read the thread you will see that I wrote what I thought was a
reasonable approach and

much of the time and in the other seems to run

I can't add anything beyond what is available on a AMD or Intel
Linux (gentoo variant).

I can't
This is a few years old, but may be useful. The code illustrates the
use of the HMAC variant on ANSI X9.17 key generation as described in the
paper, used to generate random byte strings. It uses the hash functions
in the OpenSSL libraries.
