A kernel panic because of some tweaking in the ISDN driver made it time for event-driven maintainance on the home server greenblatt. So I shut down the server, did the last syncs and removed the remaining two parallel ata disks and the promise IDE controller which was no longer needed. I re-enabled the "Cool'n'quiet" bios option so linux power saving works again, which should result in a drop in power use.
Update: As the graph shows removing the disks and re-enabling powersave has helped reducing power use.
