Yes, on the RCX. The motors can be treated as sensors.
The NXT motors can be used as sensors while plugged into an output port. By clicking on the NXT comands icon, in the new Robolab software, a selection of "Value of" icons will be avaible for output ports A, B, and C

Here are some pictures of the car used to test the program:
