Trying to determine if EC2 supports and makes available this newer instruction set.

Just fire up a t1.micro instance and test it for yourself. It would cost all of a few cents. – EEAA Feb 15 '12 at 6:19

from my testing, no. all of the ec2 instances I've tested use intel E5xxx or X5xxx cores, which don't support AES_NI. You'll need E7s for that. maybe we'll get lucky when new hardware trickles in.....

When this answer was first written, many instance types did, but not all. currently (2015-Dec-10) says "Intel AES New Instructions (AES-NI): Intel AES-NI encryption instruction set improves upon the original Advanced Encryption Standard (AES) algorithm to provide faster data protection and greater security. All current generation EC2 instances support this processor feature."
