Programming via SPI may not work if the oscillator fuses are 
mis-programmed, but JTAG, which is also available on Ethernut 1.3H, 
should still work. You may additionally try to keep the reset button 
pressed when starting the AVR Studio programmer.

This may be helpful too

If nothing works, you can send the board back to us for testing and 
possibly replacing the ATmega. This service will be free of charge for 
students/universities, except your shipping costs to Germany.
