Does FreeBSD allow access to CPU-specific performance counters
for Intel and AMD CPUs? The ones which can be used to optimize
pipeline and branch prediction things, etc.

It may well be that the decision to make a speed demon rather than a brainiac came from marketing, but the engineers didn't say "oh well, guess we've just got to fool the punters with a crap CPU", they said "fair enough, we'll make a speed demon that'll have such a high clock speed that it really will outperform the brainiac competition". ...
