over here my systems seem to start counting CPUs at #1 so on my
hyperthreaded machine both...

cat /proc/acpi/processor/CPU1/power

...and...

cat /proc/acpi/processor/CPU2/power

...work whereas using CPU0 does not.

...here's my output:

active state:            C0
max_cstate:              C8
bus master activity:     00000000
maximum allowed latency: 8000 usec
states:
    C1:                  type[C1] promotion[--] demotion[--]
latency[000] usage[00000000] duration[00000000000000000000]

...doesn't look good for power saving but then again this is a
P4EE-3.2ghz.  :)
