Hi! aesni(4) driver detects the module on Bulldozer fine. I was happy to see it first but then I found out that openssl that goes as part of FreeBSD distribution lacks AESNI engine module. There are some patches for bringing aesni into FreeBSD mentioned on forums but this in not a production-system-running approach for me. So the answer is YES - it exists, but right then NO - it does not work.
