I've just taken a look.  This OCB mode for AES looks really interesting.
Encryption and MAC in one pass! Wait, OCB is patented.  That's not in
the spirit of AES :-)  I suppose one could do a user defined cipher
suite for AES OCB, if both client and server knew about it.  Anyway...
must focus on current release.

Any word on whether it's OK to use the TLS AES cipher suite with SSLv3?

As a separate issue from whether you want to implement AES, if you do 
decide to implement it look at Brian Gladman's code at 
http://fp.gladman.plus.com/cryptography_technology/rijndael/

It is the fastest free implementation of AES that I know of, and has a 
good history and credentials behind it as you can see from the 
background information linked from that web page.
