hmmm...  I just got a message from chris, he said he will be adding
AES/Rijndael to the kernel ASAP...

According to the Rijndael spec, it seems to also function as an
excellant pseudo-random number generator...

You can find this info at:

http://www.esat.kuleuven.ac.be/~rijmen/rijndael

Section 13.4 of the Rijndael Block Cipher AES Proposal [version 2],
describes this functionality.  Based on the benchmark times of this
process, I don't think it would be a serious performance hit to do
this.  If it's going to be in the kernel anyway...

Just a constructive suggestion.
