Can you give a small example, say, using the diamonds dataset, or one of 
your own?  What's wrong with:

   qplot(carat, data = diamonds,
         facets = color ~ .,
         geom = "histogram",
         binwidth = 0.1, xlim = c(0,3))

which is Figure 2.16 in the ggplot2 book.  You can change this to be 

Unless you mean different variables completely, in which case you can 
create your own grid viewports, or possibly use the reshape package 
along with faceting.  Without a concrette example, it's hard to offer 
more help.
