I don't think it is a UNIX limitation, but a motherboard limitation (especially
if your memory is interleaved).  UNIX will use whatever your motherboard 
lets it (in other words: you will probably have a problem because the MB
won't let you have something else located in the memory range for one of its
banks of memory - although it might not complain at first (just crash later))
