OK, well I have pointed out a couple of discrepancies between the documentation and the comments in the default config file, maybe upstream is interested?
I have a better system now, which is just a script I call from cron to display a message and turn on the fan when the system gets too hot. I made the bug report because I thought it was the right thing to do, but it sounds like neither of us is very invested in this bug any longer :) (I guess it would be bad if functionality is being advertised in the package which doesn't work, because then everybody has to fiddle with powersaved before giving up and writing their script like I did. But presumably you would notice such a problem.)
