Hallo everyone,
ist there a chance for powersaving with the following CPU? And if so, what are 
the related modules to load?

Thanks a lot

Hi, I have the same question. Tryed all powersaving modules, but
no one worked.

Yes.

acpi-cpufreq for freq scaling support, cpufreq-ondemand for your
governor (may be built-in though)

acpi-cpufreq + cpufreq-ondemand works on the core2 quad I'm typing this
on...

$ cat /proc/cpuinfo

If it doesn't work for you, I'd probably blame your motherboard BIOS.

Hallo, tried this module on openSUSE 10.3 RC1:

modprobe acpi-cpufreq
FATAL: Error inserting acpi_cpufreq 
(/lib/modules/2.6.22.5-29-bigsmp/kernel/arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.ko): 
No such device

Thank you.

Depends on whether your BIOS is enabling this feature. Check in BIOS
options for any switch related to this feature. Also make sure you have
the latest BIOS for the platform.

Thanks,

Boot with the added kernel param cpufreq.debug=7 and check dmesg after
trying to load the module. Should say a bit more about what's going
awry. It works fine under a Fedora 2.6.22.7 kernel, so I think your
kernel should be fine, and I'm inclined to think its your BIOS at fault.
