With emc running (paused, or no program running), unplug the parallel port cable *on the computer end*. See if your system creeps.
I suspect the 2.6 kernel is putting the port in a tri-state mode, where noise can affect it. Perhaps 2.4 does things differently... If unplugging the cable causes creep, you could add some resistors to help. One resistor from each step signal to ground.
