I think you could do it with a P-FET, which is a type of transistor. 
A FET has three leads, a Gate, a Source and a Drain.   If you 
connected the Gate to one of the 5V lines on the power supply 
connector (best to do it through a resistor, say  5Kohm), the Source 
to one of the Ground wires on the power supply and the Drain to the 
Power-On wire on the power supply, it should connect the Power-On 
wire to Ground whenever the power supply 5V line drops to 0V.   This 
will reactivate the power supply whenever the machine turns off, and 
shouldn't affect the ADB bus, which the jumper apparently does.

Note, that the above is from theory.  I haven't actually tried it out.
