There are no schematics published for the Raspberry Pi. Only reduced schematics are available, which show connectors and parts of the power distribution circuit. You won't find that resistor in there. From the looks of it this could be a pull-up / pull-down of some sort. If I had to do this without any schematic, I would solder a 100 kOhm resistor and see if ...

The simplest of-the-shelf device to do this would probably be a low-resistance meter, using 4-terminal sensing. You could probably create your own version, but the design would be quite tricky, as the actual resistance value will be really low. Would it be cheating to use the metal plate as a core in an inductor? I'd guess that your materials show very ...
