check this out:
http://osdir.com/ml/kernel.cpufreq/2004-07/msg00012.html
from the reply, since the power management flag is at the per-core
level (check /proc/cpuinfo), all control can be done at the per-core
level, hard-ware wise. (not sure of Linux Kernel itself)
But at least 4 flags must be present (read above email): ts, ttp, fid, vid.
I must also say this is the first time I am aware of these flags too :-).
