Can't you just re-survey all survey points in the system? The newly activated, previously dormant, jump-point should then be discovered , no?
This is correct, and is what Steve intended as the primary way to find such newly activated WP. Note that this is a difference in rules from StarFire, where such WP are called "closed", and can only be detected if you see someone transiting or if you transit from the other side. Once a dormant WP has been activated in Aurora, it behaves just like a normal WP.
If you have a suspect bearing for the new race, you should survey the survey the locations on that side of the system first - this is because WP are discovered when the closest survey point outsystem (or is it insystem? I forget) from them is surveyed.

PS - Using SM mode to reset the survey points to zero to do the resurvey is in no way "cheating". This is exactly the sort of situation SM mode is intended for - where you need to do something in a corner case of the game that Steve hasn't put an explicit interface in for.
