It might be "obsolete" in that it is old, but there hasn't been any mention of enabling bcopy and similar operations in the FreeBSD kernel when using I686_CPU. Granted, this may not make a difference on Athlon64/Opteron/Core/Core2 CPUs. I haven't heard/read anything about this subject since that thread, though. Guess someone with access to a few different CPUs will have to benchmark kernels with combinations of I586_CPU and I686_CPU.
