Like say an opteron in the 2nd socket on the motherboard

It moves the cost it doesnt make it vanish

If I read you right you are arguing for a second processor running
Linux.with its own independant memory bus. AMD make those already its
called AMD64. I don't know anyone thinking at that level about
partitioning one as an I/O processor.
