Hi Jack Christensen ( Danish user, just as me ? )
Thanks for the quick reply.
That's almost the same conclusion as I came up with myself. Besides from pin 10 the ArduinoLCD also uses D0/D1 for tx/rx.
It's no problem modifying the Ethernet shield to move pin 10 -> 9 and D0 -> D2 / D1 -> D3, I can do that with a couple of jumper cables, but how to modify the Ethernet Library to the new pins used might require some heavy programming skills - anyone ?
