In 2008 Masashi YOKOTA <yokota@pylone.jp> created the virtual
battery driver found here:
http://downloads.pylone.jp/src/virtual_battery/virtual_battery-0.0.1.tar.bz2

It found use out of tree, but was never merged upstream.
Since then the test_power driver has been merged, which provides
very similar functionality.

This patch extends the test_power driver to be more dynamic
at runtime, by merging portions of the Virtual Battery Driver
by Masashi YOKOTA.

With this patch, I can tweak the values in:
/sys/module/test_power/parameters/* and watch the behavior of
the gnome power managment daemon or other battery UI software.

Just a handy driver that is used for testing purposes.
