[R-sig-Geo] spplot, polygons, and line density fill

In case my request wasn't really clear, let me rephrase:
I'd like to overlay some polygons onto a raster, by plotting with a line
density fill instead of a solid fill, as shown here
http://r-spatial.sourceforge.net/gallery/#fig15.R. Ideally I would be
able to modify the angle of the lines. I know how to do this in base
graphics, but I really need to use spplot (or willing to use ggplot2 if
that can do what I want).
Thanks in advance for any ideas!
