I would hazard to guess that a compile time option is a bit difficult for 
distributions which typically only want one kernel for all their user base. As 
that user base is typically large, they would potentially be unable to please 
everybody with a compile time option.

But I see that such a change may not be warranted at this point. Though, I see 
that discussion may rise again in the future when such new requirements for 
256 bit keys (not only AES, thanks Sandy for mentioning :-) ) are commonly 
raised.

So, let us disregard the patch until hard requirements are coming up.

Ciao
Stephan
