Hi,
I followed step by step the guide above:
http://www.gentoo.org/doc/en/power-management-guide.xml

but when I type /etc/init.d/cpufreqd start,

I'll obtain:
* cpufreqd requires the kernel to be configured with CONFIG_CPU_FREQ

My kernel config should be ok, infact:

# zcat /proc/config.gz | grep CONFIG_CPU_FREQ
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=y
# CONFIG_CPU_FREQ_DEBUG is not set
# CONFIG_CPU_FREQ_STAT is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=y
CONFIG_CPU_FREQ_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_ONDEMAND=y
CONFIG_CPU_FREQ_GOV_CONSERVATIVE=y

From /etc/init.d/cpufreqd:
if [[ ! -e /proc/cpufreq ]] && [[ ! -e
/sys/devices/system/cpu/cpu0/cpufreq ]]; then
eerror "cpufreqd requires the kernel to be configured
with CONFIG_CPU_FREQ"

Any suggestions? On the web I was not able to find any help...

Thanks in advance : )

Or not?

Did you boot into this kernel?
What arch and what version of kernel? (there have been some arches that may
report the wrong cpu number for the first cpu, which makes the check bad).

Yes, I booted into this kernel : )
pentium-m 2.6.16-r7

I'm recompiling the kernel, I've taked a look on:
http://gentoo-wiki.com/HARDWARE_Gent...Dell_XPS_Gen_2

and it seems I should compile as a module the cpufreq driver...

Thanks,

It works fine : )

Thanks a lot,

At least one of these files is missing (which one?). What CPU do you
have (cat /proc/cpuinfo)?

CPUFREQ was broken in some 2.6.16 kernels. Either step back to 2.6.15.6 or
ahead to 2.6.17-RCx... In the 2.6.17 rc's, you won't get all the possible
cpu frequencies as in 2.6.15.6, but it works.

pentium-m, but I've already solved the problem.

Thank you anyway.
