In a post on November 12, I described an experiment in which an
ATmega16-16PC ran with a 15.36 MHz crystal with a wide variety of fuse
setting, including CKOPT not programmed.  The experiment included long
traces and lots of stray capacitance at the crystal pins and I later
extended it to include a large imbalance in the load capacitors.  It always
worked.  So, it seems to me that the crystal circuit is not really so
sensitive.  I withhold an opinion about those plug-in breadboards, though.
I would not use one myself.
