We curretly have an off-by-factor-of-1000:

cat /proc/cpufreq

          minimum CPU frequency  -  maximum CPU frequency  -  policy
CPU  0         2000 kHz (100 %)  -       2000 kHz (100 %)  -  powersave


I do not have explanation why it is 2MHz - 2MHz.  On my system I removed
bug which prevented my system from being reported as 0.8MHz - 1.8MHz.  (And
modulo cosmetic uglyness, it worked).

This fixes cosmetic uglyness, adds proper copyrights, removes warning
"untested on PREEMPT" (someone tested it, and makes it easier to override
PST by user (eMachine users will need that one).
