2) It works!

3) output of "dmesg | grep -i power" :

Moreover, when monitoring the CPU frequency with ksysguard (I have a KDE
desktop), after launching a CPU-intensive process (like a "dd if=/dev/urandom
of=/dev/null"), one can see the CPU frequency jump from 1000 MHz to 2000 MHhz.

4) Dunno how to (functionaly) test this.. Anyway dmesg says :
[    0.000000] ACPI: HPET (v001 CORE   AMD64    0x00000000 CORE 0x00000000) @

> review my patch

Done. No remarks. :)

I did all these tests with an old ubuntu (feisty 7.04), with a 2.6.20 kernel. If
 more tests are needed in order to validate the Harald's patch, tell me and I
will upgrade my kernel next week.

 Florentin
