Does this sysctl adjust itself on machines with Intel SpeedStep
technology ? Based on my web searches, the MSRs which contain that
info don't seem to be documented. I've read about efforts to reverse
engineer the windows utility PRCPU.EXE, but haven't seen any results.

It'd be great if this sysctl is adjusted.
