I tried that actually.. There is a PTP enable bit. It's default is 1 (according to the AR8031 datasheet). Now guess what it's value is on the AR8033.. its also 1. Not enough.. I also tried to enable the realtime counter. well that worked too.

And yes. I've double checked the package marking. It definitely was an AR8033. So either I was just lucky, or maybe.. the AR8033 is just a relabled AR8031 ;)
