_All_ modern day processors support more than 4Gb - this was introduced in the
386 - although admittedly you had to abandon the 'flat' memory model. For the
386 the absolute limit was 64Gb if memory serves. Therefore the processor is
irrelevant - it's more dependant on the chipset. I never saw a 386 board that
supported so much memory but I remember them being availiable from about the
Pentium I era onwards.
