Possible, but someone will have to spend some time checking
connections on the board to find it. Really tedious work.

It's not R509 though since Q5-1 is U5-CS#, not Q4-3/Q5-3. :\

I think lifting a corner pin should be doable for pretty much anyone
with a little soldering experience but if you can find a 0 ohm that's
great! :)

Can you suggest some good connector part numbers? Needing a PCB for
the chip+connector is no fun either..
