The circuit doesn't depend on leakage currents or additional resistors. The gate driver is always operational by effect of the MOSFET substrate diodes.crutschow, that is an interesting circuit, do you know if it has been tested in real life? I am trying to figure out how the gate charge current makes it's way back to the battery if the NFET is off (KCL). By leakage current? This could mean a slow turn-on time depending on the FET properties?
FvM, your circuit looks like the same idea. I suppose a large-value resistor could be added between the source-source point and the battery ground to provide a better gate charge current path.

I think you can easily verify the circuit operation under different battery conditions with a circuit simulator.
I have not tested it, only simulated it......................................
