Problem with Power Saving Feature for AMD 64 Notebook

[Lyuokdea]

I just installed a copy of Mandrake for my AMD64 3400+ laptop. Everything seems to work well except that the operating system is not allowing the software to downgrade the processor speed to 800 Mhz during normal usage.

This is a big problem because the laptop is now running very hot during word processing and simple tasks like typing here. Does anybody know how to correct this problem?

I don't think 64 bit CPUs are fully supported yet.

I'm running the 64 bit edition, but regardless, I don't need the 64 bit support, I just need support for the processor to downspeed when the full Processing power is not necessary. Just the same as most Intel Pentium M's do and such.

ok, looking at the problem, I believe I need to switch my CPU driver over to a different version and then check the kernel to make sure that CONFIG_X86_POWERNOW_K8 is enabled.

Currently when I run
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
2200000
which is the full speed for the CPU.

And when I run:
cat /proc/acpi/processor/CPU1/info
processor id: 0
acpi id: 1
bus mastering control: yes
power management: no
throttling control: no
limit interface: no

So it is obvious that throttling control is currently not running. My question is two fold, first, how do check and possibly change the driver for the processor, I tried using harddrake, but didn't find any configuration module for the processor driver. Also, how do I enable throttle control if the processor driver is correct?

Thanks for your help,
