//		Revision 1.6  2003/07/08 04:32:49  eem
//		3288891, 3279902, 3291553, 3154014
//		
//		Revision 1.5  2003/06/07 01:30:56  eem
//		Merge of EEM-PM72-ActiveFans-2 branch, with a few extra tweaks.  This
//		checkin has working PID control for PowerMac7,2 platforms, as well as
//		a first shot at localized strings.
//		
//		Revision 1.4.2.5  2003/06/04 00:00:51  eem
//		More PID stuff, working towards support for forced meta states.
//		
//		Revision 1.4.2.4  2003/06/01 14:52:51  eem
//		Most of the PID algorithm is implemented.
//		
//		Revision 1.4.2.3  2003/05/31 08:11:34  eem
//		Initial pass at integrating deadline-based timer callbacks for PID loops.
//		
//		Revision 1.4.2.2  2003/05/26 10:07:14  eem
//		Fixed most of the bugs after the last cleanup/reorg.
//		
//		Revision 1.4.2.1  2003/05/22 01:31:04  eem
//		Checkin of today's work (fails compilations right now).
//		
//		Revision 1.4  2003/05/21 21:58:49  eem
//		Merge from EEM-PM72-ActiveFans-1 branch with initial crack at active fan
//		control on Q37.
//		
//		Revision 1.3.2.1  2003/05/14 22:07:49  eem
//		Implemented state-driven sensor, cleaned up "const" usage and header
//		inclusions.
//		
//		Revision 1.3  2003/05/13 02:13:51  eem
//		PowerMac7_2 Dynamic Power Step support.
//		
//		Revision 1.2.2.1  2003/05/12 11:21:10  eem
//		Support for slewing.
//		
//		Revision 1.2  2003/05/10 06:50:33  eem
//		All sensor functionality included for PowerMac7_2_PlatformPlugin.  Version
//		is 1.0.1d12.
//		
//		Revision 1.1.2.1  2003/05/10 06:32:34  eem
//		Sensor changes, should be ready to merge to trunk as 1.0.1d12.
