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?
