AMD Bulldozer and aesni driver

[图潘]

What patches are you talking about? There is an official aesni driver
http://www.freebsd.org/cgi/man.cgi?query=aesni&sektion=4&manpath=FreeBSD+8.2-RELEASE
And it does work for intel.
Sorry I didnt quite understand you fully. Do you mean it does not work
in general?
