gnome power manager does not react on low power

As stated in the gnome-power-manager FAQ

You might be able to use the percentage charge for g-p-m to use as the policy data. Open gconf-editor, and then change the key /apps/gnome-power-manager/use_time_for_policy to false. You can do this easily by doing:

> gconftool-2 --set --type bool\
/apps/gnome-power-manager /use_time_for_policy false

This should get the policy actions working for you, but of course the time remaining will still be incorrect.

My Lenovo Thinkpad X60s seems to be affected.
