I don't know if it is of any interest but I have a different result:
$ cat /proc/acpi/processor/CPU0/power
active state: C2
max_cstate: C8
bus master activity: 00000000
states:
C1: type[C1] promotion[C2] demotion[--]
latency[000] usage[00000010] duration[00000000000000000000]
*C2: type[C2] promotion[--] demotion[C1]
latency[001] usage[01409563] duration[00000000005313483434]
I have a MacBook Pro with Core1Duo and using the Debian Etch
2.6.18-4-686 kernel (no additional patch)
