Again I totally agree with you but my processor is AMD Opteron, that will make things different.

If the processor is x86 then Hugmem kernel is not necessary for the memory 16G or less, because it can take advantage of PAE also available for x86 processors only.

kernel-smp: Contains the kernel for multi-processor systems. The following are the key features:
> Multi-processor support
> Support for more than 4 GB of RAM (up to 16 GB for x86)
> PAE (Physical Address Extension) or 3 level paging on x86 processors that support PAE
