   Excuse me for the late response. I looked into Kconfig file and it looks that what you 
are saying is correct assessment.
This is what Kconfig file under arch/x86 says
---------------------------------------------------------------------------------------
config MAXSMP
         bool "Configure Maximum number of SMP Processors and NUMA Nodes"
         depends on X86_64 && SMP && DEBUG_KERNEL && EXPERIMENTAL
---------------------------------------------------------------------------------------
So this value is changed only specific to x86_64 arch

And check for ppc64 didn't reveal any modification to the MAX_NUMNODE value.

As you put it reading this value from configure file appears to be a better idea
Thanks
Sharyathi
