Sorry Henning,
axis.break may have some problems in the lattice environment. The "user
units" don't necessarily correspond to what is on the plot, nor can you
necessarily add things to a plot that is displayed. Unfortunately, I
can't get your example to run (I get "Error in as.vector(x, mode) :
invalid 'mode' argument"), so I can't suggest how you might get around
this.
