We'll also provide documentation for the new PPC functionality.  I've 
identified the following areas in the OProfile manual that should be 
changed:
       Chapter 2, "System Requirements"
           para 1: add a statement on what kernel patch level is needed
		for Linux on POWER
       Chapter 3, "Controlling the Profiler", section 1.2:   add a note
		about the event naming scheme for PowerPC (abc_GRPx) and
		how the user must specify events from the same group.
       Chapter 3, "Configuration Details", section 3 -- add a "PowerPC'
	      subsection between 3.5 and 3.6.
