BTW: It seems that my processor does not use the C1 state!

$ cat /proc/acpi/processor/CPU/power:
active state: C2

bus master activity: ffffffff
states:
C1: promotion[C2] demotion[--] latency[000] usage[00000010]

Hardware: T40p with Pentium-M 1.6 GHz.
Everything seems to work perfectly well.

$ cat /proc/acpi/processor/CPU/performance:
state count: 6
active state: P0
states:
*P0: 1600 MHz, 24500 mW, 500 uS
P1: 1400 MHz, 21000 mW, 500 uS
P2: 1200 MHz, 17000 mW, 500 uS
P3: 1000 MHz, 13500 mW, 500 uS
P4: 800 MHz, 9500 mW, 500 uS
P5: 600 MHz, 6000 mW, 500 uS
