Surely it wouldn't be added here if some could supply 0.9v. Is the code that uses this smart enough to sensibly switch between two operating points with the same frequency and different voltages? If so, maybe just add a 144MHz @ 1.0v operating point? (Alternatively, would it make sense to modify the code that uses this to use frequencies with voltages specified that are lower than can be supplied with the lowest voltage it can?)
