I'm not worried about any damage unless the "Low Oil Pressure" warning comes on. My interpretation of that is either the pump driveshaft is properly connected to the rotor and normal oil pressures are maintained or it separates and loses all oil pressure immediately (catastrophic failure of the pump) - there's no "in between" where you have "low" oil pressure.

Agreed. The e36 m3 also suffers from a similar oil pump fate, in the form of the oil pump nut backing off randomly. It's one of those things where no matter how much you baby the car, how hard you abuse it, when it happens it happens. Not a slow degradation/breakdown of the engine's internals. One minute the engine is 100%, the next it is 0. I would assume the m5's problems are of a similar vein.
