It looks like the line
if ( pidofproc $DAEMON 2>&1 > /dev/null ) ; then
in /etc/init.d/cpufreqd is at fault. Commenting out that line (and the
associated "fi") makes the script work as intended. The function
pidofproc comes from lsb-base and indeed, there have been changes in
that area recently:
* Fix killproc() to work if signal isn't specified; also fix the
pidfile check in both killproc() and pidofproc(). (Closes: #370075)
This fix however seems to brake cpufreqd's init script.

Yes, but does the kernel configuration allow for such detailed profiles
like "performance when on AC, performance when on battery and still
over 50 %, then ondemand and when below 20 % of battery powersave"?
This is the nice thing about cpufreqd. You can even define exceptions
to general rules when certail programs are executed etc.
