okdok
folks first check acpi is supporting temperature and
throttling
by cating
 /proc/acpi/thermal_zone/ATF0/temperature
then
/proc/acpi/processor/CPU0/throttling
(state - is normal)
you can set the throttling state by (say)
echo 4 >/proc/acpi/processor/CPU0/throttling
to set state 4

The script is very crude but it keeps me knees cool:)
run in  xterm as root.
hope its useful to someone

cheers,
Rob
