Is it really good idea to autoload crypto modules? Currently loading
different cipher implementations is handled via module-aliases and
cipher priorities. With autoloading by CPUID, crypto-modules would be
loaded and be mostly unused. For example, serpent-sse2 would be
autoloaded on all x86-64 kernels (well, on those that have it compiled
as module => probably most of distros).

IMHO these should be loaded only when needed, as is done with generic
i586/x86-64 assembler cipher implementations.
