Package: linux-2.6
Version: 2.6.25-6
Severity: wishlist

Hi,

desktop x86 cpus before Core 2 Duo don't have (enhanced) speedstep, so they
can't use acpi-cpufreq nor speedstep-centrino to do frequency scaling. 

However, they can use p4-clockmod to do frequency throttling, which is not as
good as frequency scaling but still can be useful.

http://www.kernel.org/pub/linux/utils/kernel/cpufreq/hardware.html has a list
of which hardware is supported for which module.

So it'd be nice if CONFIG_X86_P4_CLOCKMOD (and CONFIG_P4_CLOCKMOD on i386 I
guess) could be enabled.

Cheers,

This has been enabled some time ago, it's present since 2.6.26 onwards:

jmm@galadriel:~$ dpkg -L linux-image-2.6.26-1-686 | grep clockmod
/lib/modules/2.6.26-1-686/kernel/arch/x86/kernel/cpu/cpufreq/p4-clockmod.ko
