In addition to my last mail: It recurred to me that Christian Kujau benchmarked this patch already.
aes, C impl., http://nerdbynature.de/bench/prinz/2.6.0-test6/crypto/test_1/prinz-2.6.0-test6-aes.txt aes-i586, http://nerdbynature.de/bench/prinz/2.6.0-test6/crypto/test_2/prinz-2.6.0-test6-aes.txt
20% - 50% throughput gain. Avg. latency is also much better.
