Using motor as sensor

This probably came up before, but it may not.

The (new type) 9V motor can be connected to a sensor input. If it's set as a
light sensor, it will power the motor (low power, but usable). When the
motor is stalled, its resistance will raise the sensor reading to 100, thus
doubling as a sensor.

This would be very useful (saving a scarce output port), if only we could
change the polarity of the power.
Still the sensor reading may be useful to measure the load of the motor (?)

Any idea if this can hurt the RCX?
