Probably no more insane than loop unrolling, which I understand is fairly standard and well-accepted.

Loop unrolling is actually becoming somewhat of an outdated technique for modern processors:

http://www.agner.org/optimize/blog/read.php?i=142 "It is so important to economize the use of the micro-op cache that I would give the advice never to unroll loops."

I don't know how AMD compares.
