Because I wasn't sure if S_B was the right pin to be testing, I also tested the three 5.3V pins. Those all read 0V.

When I connected the cable that leads to the buttons on the front bezel, and pushed the power button, I noticed at most a 0.1V drop, but I wasn't sure if that was from my unsteady hands, the decreasing voltage behavior I mentioned above, or what. Pressing the power button repeatedly did not cause the voltage to go down any further, nor would it go back up 0.1V. I tried to wait until the PSON voltage stabilized before pressing the button, but it was a little difficult holding the leads with one hand, pressing the button w/ the other, and staying steady enough to read the DMM. If you like, I can try it again when my wife gets home to help me out.
