Yakui, Did you actually check if the above was true?

What is the name of the driver? I'm not able to find any such driver
in Fedora 9 installed modules. There is only acpi-cpufreq and powernow-k8.

Also, If someone doesn't mind, can they tell me what all files I need to
replace in Fedora 9 once I get a kernel.org kernel compiled? I know
how to edit grub.conf,
and that I should replace vmlinuz, but do I need to replace initrd too?

Thanks,
