Does FreeBSD currently support cryptographic acceleration for AES on the

(most things in open source happen because someone needs it.)
I found Linux's code: http://lwn.net/Articles/311094/
I think that it looks too easy, maybe, we should implement aesni(4)
like padlock(4).
I was thinking that if I did do it, I'd start with padlock as a base.
It looks like there are maybe 6 new opcodes. Maybe we could ask the
contributor of the Linux code (an Intel employee) if he'd be willing to
also release the code under a BSD license.
My problem is that I don't have a Core i5 system--I was asking because
it's an option for my new system--and I'm far from an x86 assembly expert.
