How much will Apple have to change the operating system in order to let
MacOS X and MacOS Classic {68K emulation including} run on an Intel
processor?

Remember that MacOS has always run in big-endian mode and that Intel has
always run in little-endian mode. MacOS would have to emulate
big-endianness for old programs just as VirtualPC for G5 has to emulate
litte-endianness on the G5 {earlier PowerPCs could run both ways}.
