I get diagonal striping.

I seem to remember that the diagonal hatched fills were disabled or  
not brought over to lattice from base S graphics because they were  
thought to be causing cognitive distortions[1,2]. You already seem to  
be able to specify the color of the fill, and it's easy to get  
alternating colored fills with col = c("grey","red") ,  so it's not  
entirely clear what your unsatisfied goals are.
