What cypto algorithms do you need?  Stream encryption and/or PKI KEX?

For AES stream encrpytion there are some CPU's that directly support
the crypto primitives on the silicon.  For newer x86/amd64 CPU's see:
  http://en.wikipedia.org/wiki/AES_instruction_set

A number of VIA x86 CPU's have supported a set of crypto algorithms
inlcuding stream cyphers, cryptographic hashing and RSA for quite some
time on their silicon.

Other than that there are some embedded crypto engines with their own
(mostly MIPS based) single and multi-core CPU's.  AKAIK they have a
FreeBSD API and the FreeBSD MIPS port should work on at least some of
them:

Cavium also has some plug-in crypto accelerator cards under the brand
name Nitrox.  IIRC they have some drivers for FreeBSD available.
