after your recent posting i had a closer look at my raq here, and now i'm wondering how one would get access to those jumpers. the front panel does not really seem removable to me, aren't those plastic thingies fixed?
No, they are just clipped in place. If you remove the metal top cover (all *10* screws!) and look at the back of the LCD circuit board, you'll see the plastic clips holding the bezel in place.
