OK so I am looking at my /var/log/messages because of something else but I keep seeing this:
p4-clockmod: Warning: EST-capable CPU detected. The acpi-cpufreq module offers voltage scaling in addition of frequency scaling. You should use that instead of p4-clockmod, if possible.
ooookayyyy so apparently I should use acpi-cpufreq instead of p4-clockmod? how do I do that? seems like this is something built in to my kernel so I'm not sure how to just "change" from one to the other
