This option must be switchable of course - I don't need it, too! It should be handled like the bios switch: default is without any change - machines which need it, enable it with c6package.disable e.g. or even better additionally via sysctl (always opt in).
About power consumption: I can test it on base of an already overclocked system (+200 MHz). I can do it once I can switch off the system to put in the power meter. The precision isn't very high, but 1 or 2 Watt more or less should be noticeable.
