[ I posted this to goodies-dev earlier, but got no response, so I'm posting it
here as well ]

I've got some problems with interface responsiveness in
xfce4-battery-plugin, that is - the tooltip showed up much too late, and
the configuration dialog was hardly usable - I had to wait a few seconds
after each click for the interface to react. This is due to the fact
that reading battery & AC /proc entries blocks the whole application
for ~2 seconds.

I've found two ways to solve this problem (and I think that both should
be available in xfce4-battery-plugin):

1. Reading those files in a separate thread.
2. Checking battery & AC status from /sys entries instead (which can be
read without blocking the interface). This is possible on linux
2.6.23-rc3-mm1 with some patches(*) from linux-acpi mailing list, and
should be available in stable kernel soon. I use it currently and
haven't found any bugs yet, so I thought I'd share this solution as
well.

I include both patches (they're separate now, but merging them
shouldn't be a big problem). I'm new to this project - and
open-source development in general - so they aren't probably done the
Right Way. Criticism welcome :)

Reproducible: Always
