Chaning CPU Performence

[Troy Campano]

Hello, 
I'm trying to change the speed that my processor runs at to a lower
speed, but i'm having trouble.
When I try to change the speed to speed 5, it doesn't seem to change the
speed at all.

Any ideas?


[root at insomnia root]# cat /proc/acpi/processor/CPU0/performance
state count:             6
active state:            P0
states:
   *P0:                  2400 MHz, 20000 mW, 250 uS
    P1:                  2400 MHz, 20000 mW, 250 uS
    P2:                  2400 MHz, 20000 mW, 250 uS

    P4:                  2400 MHz, 20000 mW, 250 uS
