Thanks Deepayan; I think I finally found a solution which worked much
easier than I thought:

## Thanks to "R graphics, 2nd ed" Paul Murrell, page 250 shows how to edit
## an existing plot.
levelplot(matrix(-90:89,20,20))
grid.edit("[.]colorkey.labels$", grep=TRUE, just="right",
          global=T, x=unit(0.95, "npc"))

I can live with adjusting the x position by hand.
