Yea.. that would tell you if it works.. Or.. You could time the cpu doing
something.. Like compiling the kernel??

That you would need cpudyn.. but I just dL'ed the source for cpufreqd
1.1-rc1, the feature set has indeed been inproved quite a lot. I'm rarring
to give it a go tonight or during the weekend.

Cpudyn has not been too nice to me somehow.. BUt I wouldn't rule it out, its
based on "demand" to puump up the speed.

Have a look at the new Cpufreqd!!
