They might, but not unless Apple designed the motherboard with the future in
mind. They have to have a trace for the extra address line on the
motherboard or it won't work. The 2 GB DIMM would appear as a 1GB DIMM
without that extra address line. There may also be an issue with other
motherboard support chips. I'm not an expert on motherboards, but know at
least enough about digital electronics to have a feel for what goes on. DMA
(Direct Memory Access) would mean that other devices would also need to have
access to the extra address line. Not just the CPU.
