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 0Then run
update-rc.d cool defaults 80
to enable it.
