I don't have any governor loaded when testing it, just the processor
module, without speedstep-centrino and cpufreq-* modules.

When running on AC there are 2 cstates :
# cat /proc/acpi/processor/CPU1/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[00005536] duration[00000000000041838680]

and 3 on battery :
# cat /proc/acpi/processor/CPU1/power 
active state:            C2
max_cstate:              C8
bus master activity:     20000010
states:
    C1:                  type[C1] promotion[C2] demotion[--]
latency[000] usage[00000010] duration[00000000000000000000]
   *C2:                  type[C2] promotion[C3] demotion[C1]
latency[001] usage[00007935] duration[00000000000049878469]
    C3:                  type[C3] promotion[--] demotion[C2]
latency[001] usage[00008673] duration[00000000000069020648]

Just with the processor module, frequency reported by x86info or
gkrellm-x86info goes from ~10MHz to 800MHz or 1800MHz (depending on
whether I booted on battery or on AC power).

What is strange is that it seems that I'm the only one having this issue
and only on my laptop.
