R help - Apr 2010 - Multiple cex sizes in main for xyplot?

Folks:

I would like to write two lines of text in two different font sizes (or
faces or ...) as the title ("main") of a trellis plot.  The following
code
does it, but not well:

xyplot((0:1)~(0:1),
	main = textGrob(lab=c("Some Text","Some More
Text"),y=c(.95,.8),
			gp=gpar(cex=c(1.2,1.0)))
	)

There is too much space between the title text and the plot. I assume that
can be fixed by fooling with padding settings in lattice.options(), but my
question is: Is there a better, simpler way to do this? 
Would using grid graphics directly by pushing title and plot viewports and
then adding the lattice graph to the plot viewport be a better way to go?

OS = Windows XP
R = 2.11.0 
lattice_0.18-3
device = windows

I don't think there's a much better way to do it... but this seems to
work:

xyplot((0:1)~(0:1),
       main = textGrob(lab=c("Some Text","\nSome More
Text"),x=c(0.5,0.5),
                       gp=gpar(cex=c(1.2,1.0), lineheight=2))
       )
