Patrick,
	Ok..  here are the real changes.  I'd really like to get some feedback on 
what you (or anyone else) thinks of these proposed changes.  This sets 
up a generic topology initialization routine which should discover all 
online nodes (boards), CPUs, and Memory Blocks at boot time.  It also 
makes the CPUs and memblks it discovers children of the appropriate nodes.

Cheers!
