It need to be done IMO in a driver, definitely not in cpufreq core, and
worst that may need to be adapted to the acpi perflib certainly (when
all pending patches for will go to mainstream I guess).

For now, you can adapt with something like the powernow-k7 override
patches at http://www.poupinou.org/cpufreq/powernow-k7/ if really
needed.

Also, you should check that in fact the acpi perflib stuff will give
you more accurate results.  For the powernow-k7 case, unfortunately, it
sound like that acpi perflib whereas giving good results still could be
problematics for some acer IIRC due to a bad VID for one entry, and then
it may be usefull for them to get the override patch merged IMO.
