When I issue the commands above I get:
[akonstam cyrus ~]$ cat /proc/acpi/processor/CPU0/throttling
state count:             8
active state:            T0
state available: T0 to T7
states:
   *T0:                  00%
    T1:                  12%
    T2:                  25%
    T3:                  37%
    T4:                  50%
    T5:                  62%
    T6:                  75%
    T7:                  87%
[akonstam cyrus ~]$
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
1867000 1600000 1333000 1067000 800000

Now the second set of numbers are the ones I actually see as cpu
frequencies. The first makes no sense at all. Can any one explain the
output?
