Athlon processor throttling

http://www-users.rwth-aachen.de/hendryk.pfeiffer/laptop.html

I have the same laptop described on this page. I installed kernel 2.5.51 + the latest ACPI patch. This guy describes setting throttling with echo n >/proc/acpi/processor/CPU0/throttling. Below is my attempt of changing the active state, but it doesn't appear to do anything.

[root@laptop CPU0]# pwd
/proc/acpi/processor/CPU0
[root@laptop CPU0]# cat throttling

state count:             16
active state:            T0
states:
   *T0:                  00%
    T1:                  06%
    T2:                  12%
    T3:                  18%
    T4:                  24%
    T5:                  31%
    T6:                  37%
    T7:                  43%
    T8:                  49%
    T9:                  55%
    T10:                  62%
    T11:                  68%
    T12:                  74%
    T13:                  80%
    T14:                  86%
    T15:                  93%
[root@laptop CPU0]# echo -n 9 > throttling
[root@laptop CPU0]# cat throttling

Writing to some if not all of the acpi files under /proc/acpi appar to be broken in 2.5.x tree at this time. We hope that the responsable for will soon release a proper patch.
