At one time, I was really keen on Broadcom and other crypto cards.
However, personal computers have become so cheap and powerful, that
I am able to get more than >2000 RSA private-key signatures with a
RSA key having a 1024bit modulus, just on a cheap/basic 2GHz AMD64
machine running NetBSD-amd64.

The broadcom cards you mentioned are obsolete.

So why pay so much for these cards, and deal with all of the legal
paperwork and export restrictions?  Software crypto on 64bit AMD's
should be more than enough to meet your needs.  And since a lot of
crypto libraries use 64bit math, the AMD's kick butt.

The only justification these days I have for crypto is for embedded
devices that need accelerated crypto for VPN, and smart-cards or USB
crypto-tokens that protect RSA private keys from the host computer.
