whats going on here ???
why is throtteling not supported ??

other question:
is there a way to run cpufreqd with libc 2.2.5-11.5 (debian woody -

these are parameters for the userspace governor, try echo
"0%0%100%userspace" > /proc/cpufreq

and play with them

acpi throttling is not cpufreq :) (I remember detailed discussions on
the topic either on this list or the acpi-devel one)

you could download the debian source package and make a woody deb from
it. You actually need a couple of adjustments:
- remove the debconf version dependency from the debian/control file:
  Build-Depends: debhelper (>> 4.0.0), debconf (>= 1.2.9)
                                               ^^^^^^^^^^
- modify following the line of debian/postinst from
  unset CPUFREQD_PM
  to
  [ -z ${CPUFREQD_PM} ] || unset CPUFREQD_PM

and build the binary deb as usual (see release notes on sourceforge).

write me off list if you need help
