Autopilot and autothrottles appeared to re-engage at touchdown after being disconnected (autopilot at 500 FT and autothrottles at 200 FT).  At touchdown throttles came up and F/O had [to] physically retard them.  At this point throttles would not go into reverse and aircraft looked like it was going to exit the right side of Runway 23. Capt stepped on the left rudder (acted as if autopilot was still engaged); [it] would not respond.  Hit the disconnect switches (autopilot and autothrottles) again while engaging manual brakes pretty heavy.  At this point the reversers came up; and a/c started to respond normally. Throttles were stiff; other than that I have no clue.Increase maintenance budget; better test equipment and more in depth training for maintenance folks with all the electronic systems on the aircraft.Prevention!  Better than reaction.

A310 flight crew reported that autopilot and autothrottles appeared to re-engage at touchdown after being disconnected; slowing selection of reverse thrust and affecting directional control.
