What else is there that prints this info? The gnome power manager thingy
only shows percentage, and not estimated time lately :(
Maybe I should just switch to KDE on my laptop too (I only use gnome on
my laptop because it is quicker to log in).

Are there any other hidden keys? :)

Nasty.
timidity++ was holding it open, but even after stopping it, it still
shows up as used 100%.
'lsof | grep snd' and 'lsof | grep pcm' come up empty now. Any other
device they may keep open?

Good idea.

Intel 4965 AG, I toggle the switch on the back and turned off the radio.

When the fan is running at around 1800 rpm it shows as 0, when it is
something high (as 5000) it shows as taking up close to 8 W.
