I am not talking about what they support, I'm talking about whether the CPU
can address that much physical memory. I may be wrong though, after thinking
about it and hearing the points about chip design where every pin is either
used or not manufactured. I do know there is a 64 bit virtual address space
on System Z and there is no per address space limit of 4G unlike many PC OS.
