Hmm. I reread the original post and i have to say: It's ambiguous.

What i read, and what stuck in my head, was "dmcrypt doesn't support 
AES-NI", not "my CPU doesn't support AES-NI".

But i guess the OP meant the latter, so my mistake.

wants a "you asked for it, you got it" text editor -- complicated, 
cryptic, powerful, unforgiving, dangerous.
