Sorry, I came up with this question because when compiling 
(linux kernel) I came across these lines:

For x86_64 this is recommended on all multiprocessor Opteron systems. 

If the system is EM64T, you should say N unless your system is 
                                                    EM64T NUMA.

Therefore the question if our Xeon E5345 or Xeon X3220 are EM64T NUMA or 
just EM64T.

Sorry for not being more clear initially.
