Well, I checked them all and found nothing. There are a number of signal lines but it looks like the 1.8V line isn't exposed on a test pad. I did find a pad which was directly connected to the ~4V battery, and three diodes on that brought the level down to ~2V, but ugh.

Next step: soldering to those horrifying UART pads.
