Marius,
I think that you mean something like the following:

  U <- matrix(runif(300), ncol = 3)
  splom(U, par.settings = list(
                 axis.components = list(
                     left = list(pad1 = 3)
                 )
           )
  )

which will adjust the left axis; you'll have to add
right, top, bottom components to handle those as well.

Have a look at what trellis.par.get() produces and
check the axis.components section.
