1. You didn't give enough space for the ylabels.
2. See ?ps.options and use trellis.device(..., color = TRUE).

ps.options(paper = "a4", horizontal = TRUE,
           colors = ps.colors.rgb)
trellis.device(postscript, file = "problem.eps", color = TRUE)
par(mar = c(5, 15, 3, 1))
barplot(rpois(5, 2),
        names = rep("A very long label with tildes mamá!", 5),
        horiz = TRUE, col = 10)
dev.off()

This works on S-PLUS 6.2 for Windows.
