[PATCH] Config file for laptop mode.

[PATCH] Config file for laptop mode.

From: Dax Kelson <dax@gurulabs.com>

Add support for a external configuration file for /sbin/laptop_mode, and
/etc/acpi/actions/battery.sh.  Convert battery.sh to use CPUFreq (off by
default) instead of CPU throttling (that was off by default).

Cleanup some formating for 80 columns.

All changes were written by me on a plane flight from Philadelphia to Salt
Lake City on July 9th.  :)

(Note from Bart Samwel: was submitted to Linus earlier, this patch is
unchanged from that.  I needed to submit this into -mm for now because my
other changes are dependent on Dax's changes.)
