 Kernel driver ibmaem
 ======================

 Supported systems:
-  * Any recent IBM System X server with Active Energy Manager support.
+  * Any recent IBM System X server with AEM support.
     This includes the x3350, x3550, x3650, x3655, x3755, x3850 M2,
     x3950 M2, and certain HS2x/LS2x/QS2x blades.  The IPMI host interface

-This driver implements sensor reading support for the energy and power

-The v1 AEM interface has a simple set of features to monitor energy use.
-There is a register that displays an estimate of raw energy consumption
-since the last BMC reset, and a power sensor that returns average power
