You should be able to specify absolute dimensions for the annotation
elements using ?lattice.options (also settable through the
'lattice.options' argument in xyplot() etc.). For a list of legitimate
component names, see

str(lattice.getOption("layout.heights"), max.level=2)

Each component should be a list of arguments to grid::unit().

Due to a bug this doesn't work properly in the current released
version, but should be fixed in the r-forge version available at
