sounds cool
I have one athlon 4 on one KT133.
but after reading 
http://cip.uni-trier.de/nofftz/linux/Athlon-Powersaving-HOWTO.html

in 2.5
This is the only solution which does not use the ACPI system of the
Linux kernel. 

in 3.1. Known Bugs/Problems
There could be following problems (caused by the bugs):
      skips during sound playback
      skips and slowdown during video playback
      slowdown of the ultra-DMA harddisk transfers
      system hangs

what could be worst ? :-)


2.1. The Command-line Hack
you can enable/disable the power-saving right from the command-line
without any need for rebooting.

on KT133/133A, KX133, KL/KLE133, KM/KN133, ...:
enable: setpci -v -H1 -s 0:0.0 52=$(printf %x $((0x$(setpci -H1 -s 0:0.0
52) | 0x80)))
disable: setpci -v -H1 -s 0:0.0 52=$(printf %x $((0x$(setpci -H1 -s
0:0.0 52) & 0x7f))) 

How I know if it enable or disable ?
is it safe try this commands?

thanks in advance
