Athlon processor throttling

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
state count:             16

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.

And yes, we know who have broken, and we will soon go to his home
and brrr, I hope we will be not too nervous :)

Cheers,
