That's interesting... Look like you could use the flash chip's EUI-48 as your ethernet MAC address...

Is the P2 fast enough to speak MII, RMII, or even RGMII?

As far as transfer speeds go, MII is 25 MHz nibble oriented transfers. The P2 can do this even with bit banging, though overclocking will help as will making use of the streamer. I believe ozpropdev is bit banging a 8 bit HyperRAM bus faster than this.
RMII is two bits at 50MHz. Probably quite doable as well but more shifting is needed and there are not really that many native instructions to work on two bit quantities unlike nibbles, so you might need to accumulate them in software somewhere with your own shifting and that adds overhead. The streamer does have support for two bit quantities so it might do this for you.
RGMII is 125MHz 4 bit DDR. This could be pushing the P2 a bit on receive side processing but raw transmission out at this speed could be doable, given the chip is already capable of outputting DVI data at a similar 250Mt/s. You may of course then have to start to deal with signal integrity issues and board layouts etc.
