I believe that not all Nehemiah's support AES -- only those with Stepping 8
and higher, IIRC.
Yes, it's true. Here's Google's HTML version:
<http://64.233.167.104/search?q=cache:7USV0yftf9wJ:www.via.com.tw/en/images/Products/eden/pdf/PadLock_ACE_prog_guide.pdf+Nehemiah+stepping+AES&hl=en>;
of the VIA ACE programming guide:

If you're not Stepping 8 or higher, you only have the (P)RNG.
