From f61e34fce870f45136a2cfcb73133b63df5321af Mon Sep 17 00:00:00 2001
From: Alan Coopersmith <Alan.Coopersmith@sun.com>
Date: Wed, 27 Jul 2005 00:34:57 +0000
Subject: Switch xload on Solaris from libkvm to libkstat so it works with both
     32-bit and 64-bit kernels, and without group kmem. Add #include    
 "config.h" for modularization
