kapm-idled is merely a daemon that graps all free CPU time and runs instructions to help keep the CPU cool. So if you system is not doung much, kapm-idled is supposed to use a lot of CPU.

This little utility will cool your Athlon/Duron processor on Via KT133 or KX133 (VT8363 or VT8371/VT82C686x) chipsets during idle.

It seems that a simple HLT instruction will halt a Athlon/Duron but it will not put it into a low power mode.

Even setting the Bus disconnect bit in the Northbridge is not sufficient because the Northbridge will only take action if the CPU is in the STPGNT state - a mere HLT just isn't enough.

	the AMD 761 Northbridge has an option for disconnecting the bus on HLT. To put the CPU into the required STPGNT state you'd have to utilize an ACPI register in the Southbridge.
