Unfortunately it's not particularly easy in the current version.  In
the next version, you can do:

p <- qplot(wt, mpg, data=mtcars, colour=cyl)
# Get the plot grob
grob <- ggplotGrob(p)
# Modify it place
grob <- geditGrob(grob, gPath("strip","label"), gp=gpar(fontface="bold"))

# Draw it

I think in the current version you can do

qplot(wt, mpg, data=mtcars, colour=cyl)
grob <- grid.grab()

and then follow the remaining steps.
