Package: cpufrequtils
Version: 006-2
Tags: patch
I had a look at the powernowd-1.00/debian/cpufreq-detect.sh file in
Ubuntu powernowd package version 1.00-1ubuntu5, which the loadcpufreq
init.d script is based on, to see if there had been any updates. This
is the relevant patch. Apparently Ubuntu now loads the
speedstep-centrino module for Intel CPUs with the est flag, and only
load the e_powersaver module on VIA CPUs with the est flag (perhaps
this is the solution for #566214?).

The changes might be kernel version dependent, but as far as I know
Ubuntu use the same kernel version as Debian for their next release.
Happy hacking,
