oh...typo (copy wrong messgae).  I already tested the p4-clockmod.ko just now.
both is outputted same message: (do again)

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

# modprobe acpi-cpufreq.ko
FATAL: Module acpi-cpufreq.ko not found

# modprobe p4-clockmod.ko
FATAL: Module p4_clockmod.ko not found

--------------------------------------------------

I first tried the acpi-cpufreq.ko because the module is recommended by
kernel 2.6.20+. After not effect, I also tried the p4-clockmod.ko since
my machine is intel processor:

And, I grep the "est" in /proc/cpuinfo, and it is there. so, the cpu hardware
should have opened the support.

And help?
