Vincent,
   
Is there any chance that the tracks have not been cut immediately on the
other side of the crystal pins? It's worth ensuring the oscillator is
not loaded by long strip tracks, if another crystal doesn't fix it. 

The only time I've had an AVR not immediately oscillate at 16 MHz, I'd
forgotten to set CKOPT. Any old crystal out of the junkbox seems to
work, too, so the road should be smoother once you're over this hump.
