Qantas B744 Total electrical failure?

[NSEU]

If one generator was operating, was it feeding all busses? If not, there may have been a slight degradation of proper flight control. Lower Yaw Damper? Speedbrake Flight Detent? Aileron Lockout? (overcontrol at higher speeds)

Edit: re Aileron Lockout... In the (latest) BKK incident, this would mean undercontrol at lower speeds if DC Bus #2 had no power.
