Same result.

The p4-clockmod is not in
/lib/modules/2.6.29.3/kernel/arch/x86/kernel/cpu/cpufreq/.

But I tried the acpi-cpufreq.ko and got the same result.


--------------  dump of screen ----------------

# ls /lib/modules/`uname -r`/kernel/arch/*/kernel/cpu/cpufreq
acpi-cpufreq.ko

# modprobe acpi-cpufreq
FATAL: Error inserting acpi_cpufreq
(/lib/modules/2.6.29.3/kernel/arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.ko):
No such device

Any help?
