I have already implemented that. I'm waiting for Marcelo to release 2.4.27
kernel, and I then will release loop-AES-v2.1c that includes AMD64 optimized
assembler implementations of AES and MD5. It is all tested and ready for
release.

AMD Opteron 1593.7 MHz, gcc-3.2.2

AES C implementation:
key length 128 bits, encrypt speed 690.0 Mbits/s
key length 128 bits, decrypt speed 711.8 Mbits/s
key length 192 bits, encrypt speed 588.3 Mbits/s
key length 192 bits, decrypt speed 607.4 Mbits/s
key length 256 bits, encrypt speed 507.7 Mbits/s
key length 256 bits, decrypt speed 527.0 Mbits/s

AES assembler implementation:
key length 128 bits, encrypt speed 1106.6 Mbits/s
key length 128 bits, decrypt speed 1107.0 Mbits/s
key length 192 bits, encrypt speed 932.3 Mbits/s
key length 192 bits, decrypt speed 933.3 Mbits/s
key length 256 bits, encrypt speed 807.8 Mbits/s
key length 256 bits, decrypt speed 813.7 Mbits/s

MD5 C implementation:
md5 IV speed 1381.8 Mbits/sec

MD5 assembler implementation:
md5 IV speed 2367.1 Mbits/sec
