So far my lab-power-supply at 5.3V, which results in 5V at the raspi test-points seems to have stabilized the power issues so far. If there is anymore trouble in the USB area I will shortcut the fuses. There are also people that bypass the raspi printed circuits and hook up the onboard USB-power with copper wires directly. We'll see...
