I've been following that thread on ubuntu-devel@.
When I added it to the seed, the server was not yet using on-demand
cpu frequency scaling by default at boot. Adding powernowd solved
that for us (at the time).
But yes, you are correct, Martin. As of kernel 2.6.28-8.24, powernowd
should not be necessary.
I verified this on my Ubuntu server by uninstalling powernowd,
rebooting, and seeing that:
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
And I have verified that Scott has removed them from the server seed.
