For some reason, I don't have cpufreq scaling enabled:
damon@dam-main:~$ sudo powernowd -d
PowerNow Daemon v1.00, (c) 2003-2008 John Clemens
/sys/devices/system/cpu/cpu0/cpufreq/affected_cpus: No such file or
directory
err=2Found 2 scalable units: -- 1 'CPU' per scalable unit
/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq: No such file or
directory
PowerNowd encountered and error and could not start.
Please make sure that:
- You are running a v2.6.7 kernel or later
- That you have sysfs mounted /sys
- That you have the core cpufreq and cpufreq-userspace
modules loaded into your kernel
- That you have the cpufreq driver for your cpu loaded,
(for example: powernow-k7), and that it works. Check
'dmesg' for errors.
If all of the above are true, and you still have problems,
please email the author: clemej@alum.rpi.edu

Hey S. Keeling. Thanks for the replay, always nice to hear from you
going back to the Libranet days. However, I figured this one out. User
error. My bios had "Cool and Quite" turned off. I did not catch that,
I was looking for some other bios settings. I really am not a big fan
of cpufreq scaling, however, I figure it saves my on the power bill, but
I keep forgetting to turn it off when I fire up a vm (vms hate cpu freq
scaling). Just trying to do my small part to keep Canada cool by not
heating up the US SE.

Makes me wanna reboot and hunt around for Cool and Quiet.
I usually have this on 525 MHz using "ondemand" governor. Damned near
every flashy news story or youtube video spikes cpu to ca. 90%.
I've never noted it ramping up cpu Mhz to handle the extra load, but
then, I don't know what either it or I am doing here. Sucks.

No such animal on an HP dv4 laptop.
