I'm in the midst of replacing most of the coolant hoses in my 951, and as a result I've got more stuff removed from the engine bay than usual in order to get to some of the hoses. So while peering into depths I don't usually see, I spotted this sensor sticking out of the turbo downpipe. Is that the standard narrowband O2 sensor?

Yes, stock O2 sensor.

Thats not the stock location, its usually on the crossover pipe..

That looks like my 86 where it is down under the turbo. Tough to see from above.

I may have gotten my terms mixed up. The pipe the sensor is connected to is the one that comes out from the side of the turbo; the Pelican Parts "Turbo Removal and Replacement" instructions calls it the charger inlet or exhaust to turbo flange.
