Try turning off the Supercalar mode. This sounds like a problem with the 060 setup. No other 060 has issues like this, and as long as there is memory at $0000000 (which has to be the case because the execbase is there) then it should work. It doesn’t matter if that is chip memory, in fact if you have a MMU (which you do) then that lower 4K is likely mapped to fast memory.
