the situation is indeed a bit confusing with openssl 1.0.1. Aesni
isn't a module anymore, so the hardware accel options no longer
apply. Tor master (not yet in any released version) automatically
makes use of aesni as supported by openssl 1.0.1, so either upgrade
to recent git or wait for the next release.

You'll then gain support automatically.

CC'ing Nick here to sanity-check my understanding, I haven't been
following development too much in the past few days :/
