Sent half written mail.. sorry.. will continue from where I left.

Now, this is how I understood these two different variables:
- cpuinfo.max_freq: maximum frequency (in kHz) which is
supported by this CPU
- policy->max: Maximum frequency forced by user or governor

When somebody sets policy->max, he expects cpufreq core to
use the range between min and max as the slope cpufreq core
has and adjust its frequencies accordingly..

Don't know if I am right or wrong :(
