The way the jumpers are lined up top and bottom like that is reminicent of the older style of Common Anode/Cathode LED numerical displays. I remember configuring one of these on a system about 6 years ago, and (If I remember correctly) each of the jumpers represents one 'section' of one number. Ya know, each digit is 7 LED's, etc, etc. There are no obvious components mounted on the board, so my guess is that it's designed for either an 'on mobo' chip to drive it, or (more likely if memory serves) it just takes a basic DC input, and feeds it to all the jumpers, the closed jumpers using the voltage to illuminate the LED's.
