The http://www.daniel.nofftz.net/linux/Athlon-Powersaving-HOWTO.html page describes setpcihacks for different chipsets.
This is for the KT600 only
I create this script in `/etc/init.d/cool`
#! /bin/sh
N=/etc/init.d/cool
set -e
case "$1" in
start)
# Turn on Athlon powersaving for KT600 chipsets
# from http://www.daniel.nofftz.net/linux/Athlon-Powersaving-HOWTO.html
setpci -v -H1 -s 0:0.0 D2=$(printf %x $((0x$(setpci -H1 -s 0:0.0 D2) | 0x80)))
setpci -v -H1 -s 0:0.0 D5=$(printf %x $((0x$(setpci -H1 -s 0:0.0 D5) | 0x02)))
;;
stop|reload|restart|force-reload)
setpci -v -H1 -s 0:0.0 D2=$(printf %x $((0x$(setpci -H1 -s 0:0.0 D2) & 0x7f)))
setpci -v -H1 -s 0:0.0 D5=$(printf %x $((0x$(setpci -H1 -s 0:0.0 D5) & 0xfd)))
;;
**)
echo "Usage: $N {start|stop|restart|force-reload}" >&2
exit 1
;;
esac
exit 0
Then run update-rc.d cool defaults 80
to enable it.
