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.
