   Actually, it would be useful to know which signals are available from a
trace on the surface. With "only" the schematics and component placement
available, you're pretty much out of luck unless the signal happens to be
available at a test point, resistor, capacitor or some other component with
exposed terminals. The Big-C buzz fix is an example of a mod which makes use
of a surface trace.
