Peter, do you really think there are that many ? I think I only saw
AES-NI on recent 64-bit capable chips, and it's been a while that
users have been installing 64-bit distros on such machines. Note that
I'm not advocating for breaking existing setups, just that I'm surprized
by this combination (aes-ni + 32-bit).
