[PATCH] SGI Hotplug: Incorrect power status 

This is a repost of a patch submitted by Prarit Bhargava on 01-19-06 that
never got integrated.

The get_power_status function is currently reporting a bitwise mapping of
the slot if the slot is powered on.  It should return 1 if powered on and
0 if powered off.
