The information to do this is located in various places of :

?bwplot and
?panel.bwplot
?grid.text   # linked from help(bwplot) .../main, and needed for  
fontsize  argument

bwplot(voice.part ~ height, data=singer,
          xlab=list(label="Height (inches)", fontsize=60),   # silly  
value
          scales=list(cex=1.5),
          par.settings=list(box.rectangle=list(lwd=2)))

The scales arguments are the one I have most often needed to use. One  
can separately alter the x= and y= settings if needed.
