Yes, I ran into this problem.  It's actually possible to do for
specific types of postscript files, but I couldn't figure a good way
to do it in general, especially given that psrev (or a similar
program) may decide to re-order the file.  (E.g., there was one posted
a while ago that would do what you wanted for files output by a
specific TeX postprocessor.)  If you know you won't have psrev
screwing things up, you can modify showpage to draw the DRAFT string
after it actually does the show, and then draw one instance of the
string before you get started.
