I was thinking of hacking an off the shelf force feedback joystick.

That pinout posted above is for a generic gameport. The joystick ports on the OI are slightly different. On ports 1&3 pins 5,8,9,15 are outputs designed for driving small LEDs. on ports 2&4 they are inputs for buttons. The diagram posted above shows these as being +5v which is incorrect for the OI. It is possible to configure these pins to output a voltage on ports 1&3, but they are current limited to 10ma each. That only gets you 80ma in addition to whatever small amount of power is available on pin 1 (5v). A standard lego motor draws a stall current of 300ma @ 5v according to http://www.philohome.com/motors/motorcomp.htm.
