Feed all lines through diodes into a small capacitor (you want it small so you don't drag everything low as it charges when power is first applied). You won't get 5V this way, but anything that will run on power stolen from the serial bus is going to be CMOS, and that tends to run happily at fairly low voltages anyway. Steal VERY little power. These are open collector signals with resister pull-ups, if I remember correctly. You won't be able to draw much current before the lines get pulled too low, and everything stops working.
