kpowersave & ACPI

I have a problem with kpowersave and ACPI on my T60p. kpowersave complains about missing ACPI support, battery status is not shown (it's always on AC, even when AC is disconnected). I can retrieve the battery status with acpi: $ acpi -b Battery 0: Discharging, 98%, 02:16:03 remaining Has anybody a clue what I am missing? It's running wheezy and TDE 3.5.13. acpid is running, thinkpad relevant modules are loaded, hal-trinity is installed, too. Nik
