...except that conservative has the same latency threshold as ondemand,
which I'm sure wasn't supposed to be the case. I've added the cpufreq
list to Cc:.
(Summary: p4-clockmod had its latency changed to avoid ondemand using
it, which was done to avoid the performance impact that ondemand
generates on p4s. I thought that conservative was still supposed to work
here, but as it has the same latency threshold it doesn't)
