Right. Looks like the horizontal paddings are to blame now. The
defaults are in terms of  "snpc" units, which produce different
physical units. The simplest workaround is to set them to 0 too, e.g.

theme.novpadding <-
  list(layout.heights =
       list(top.padding = 0,
	    main.key.padding = 0,
	    key.axis.padding = 0,
	    axis.xlab.padding = 0,
	    xlab.key.padding = 0,
	    key.sub.padding = 0,
	    bottom.padding = 0),
       layout.widths =
       list(left.padding = 0,
	    key.ylab.padding = 0,
	    ylab.axis.padding = 0,
	    axis.key.padding = 0,
	    right.padding = 0))
