Alas, no. The ethernet socket and the board Rx leds light up on ping, so the packets
are getting there - the (standard example) sketch simply hangs on boot.
Looking at the bus with Wireshark shows a very odd DHCP packet as the first thing
the Arduino sends, so the next problem is to find out what's going on there.
I'd hoped the Arduino software would be a bit more reliable by now, but that's life.
