On 2.4 kernels on Debian, there is a driver that enables better powersavings for AMD760MP and AMD-760MPX (usually found on multi-processors mainboards such as Tyan S2460, S2462 and S2469) chipsets:
amd76x_pm. It also exists as patch for the 2.6 kernel, but as it is non-standard, it is not included in Debian kernels packages.
To use it, simply add the following line to the end of your /etc/modules
:
amd76x_pm
To load it without rebooting, simply type the following command as root:
# modprobe amd76x_pm
Warning: Doing this on a Tyan S2469 running Debian Sarge with kernel 2.4.27-1-k7-smp
will result in hanging the machine!
