Even with the correct phymask, you cannot attach and use two simultaneous PHY on a single ethernet interface so i think that the phymask=0 is correct for this board. And no, the phymask on the ROUTERSTATION.hints is correct (0x3 << 16 == PHY 16 and 17) as there are only two ports connected on the switch (all the others PHYs on the switch are disconnected). I'm not sure about the correct miimode for ROUTERSTATION, but i think you're right, it should be RMII. I don't have physical access to this board anymore to test it myself (although a friend of mine has one of these).
