this is slightly overbroad, since no one said that the net-dimm has to 
implement a flat addressing scheme.  that is, that the only addressing bits
come from the normal row/col addresses used in the standard dram protocol.

suppose, for instance, row/col merely selected the destination node, and the 
first 64 bits of the data burst defined the memory address (in the destination
node's address space).
