@Numbski:
billm, I hope you're wrong about this. Here's why:
I have a client that needed some serious entropy available to an application. We purchased a hifn card to supplement /dev/random. FreeBSD does not create /dev/hwrandom, and from all appearances, speed of the customer's application went waaay up, and the deployment passed some certification process that I was not involved in. So….hmm.
Interesting stuff. Perhaps I should dig into this further? BTW, another option if I recall correctly would be to insert a sound card, get the driver working, get the block device for the mic-in, then take and have that constantly dumping to /dev/random too. (don't hold me to that, never personally tried it!)
You're probably correct.
