Some relevant FreeBSD changes (ty Justin)...

https://svnweb.freebsd.org/base?view=revision&revision=273872

IMHO, it really is (for BSD land, anyways) about trusting software to do
what's right with that hardware.

We've had the threads before onlist and informally about usb/hardware
entropy devices.

I don't doubt hardware can have a role, if it's done correctly and openly.

(anyone read "The Traveler" by John Twelve Hawks?)

But ultimately in this day and age, it's the software, ie, a more
trusted, audit-able platform, that should be determining the parameters
of that extra entropy being utilized.  An OS can be audited, mtree'd,
whatever, while auditing the code and confirming what's on the actual
device is a bit trickier.  Go read some of the Snowden disclosures about
3-letter-government agency hardware hacking.  It's ugly.
