I would have a look at the layout.heights trellis parameters and set
these to suit - in this case probably just the xlab.key.padding value.

Look at the list of parameters with

   trellis.par.get("layout.heights")

# (or wrap this in str() for a briefer output).

Then include a par.settings argument in the xyplot call:

   xyplot( 1 ~ 1,
          par.settings = list( layout.heights = list(
               xlab.key.padding = 5 )),
          key = list( .... etc
