No, we removed p4-clockmod from being installed on desktop machines, due to
the number of problems it was causing people.
If your machine is a laptop, then it's being incorrectly identified; please
send me the output of `sudo dmidecode`.
The message that powernowd puts out is a bit missleading; I should probably
fix that for this case.
