SOLVED: multiple lattice-pages (development package!)...

Not seen at first reading, there is one arg in trellis.args:

  page: a function of one argument (page number) to be called after
          drawing each page. 


so something like:

xx <- data.frame(x=rnorm(100),y=rnorm(100),g=as.factor(round(rnorm(100))))
tmp <- 1
xyplot(y~x|g,data=xx,layout=c(1,1),page=
       function(...){
         dev.print(postscript
                   ,file=paste("/tmp/test",tmp,".ps",sep=""))
         tmp <<- tmp + 1
       }
       )

One big thank to the people, who provide "lattice" + "grid"!
