We'd been having a problem with our 16-way x440.  The problem was, it 
wouldn't boot. :(  We've narrowed it down to an array bounds problem, 
and here's the patch against 2.6.0-test2 that fixes it.  This also 
cleans up some code that was ugly.

* There was an #ifdef'd call in setup_arch.  It's been moved into 
subarch code.

* There were some ugly for loops that now are more readable.

* The NUMA-specific code is now only compiled in & executed if CONFIG_NUMA.

* The code checks that MAX_NUMNODES has a sane value before proceeding.

Cheers!
