	  There are four families of PowerPC chips supported.  The more common
	  types (601, 603, 604, 740, 750, 7400), the Motorola embedded
	  versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the AMCC
	  embedded versions (403 and 405) and the high end 64 bit Power
	  processors (POWER 3, POWER4, and IBM PPC970 also known as G5).
	  
	  Unless you are building a kernel for one of the embedded processor
	  systems, 64 bit IBM RS/6000 or an Apple G5, choose 6xx.
	  Note that the kernel runs in 32-bit mode even on 64-bit chips.
