Yes. If you use latex + hyperref with the dvips driver, one gets most of
the functionality of hyperref (the only exception I know of is that
links cannot extend over a linebreak). One needs to run dvips with the
-z option.

Well, hyperref has a "hypertex" fallback, which produces specials
understood by several .dvi viewers (and dvips, I think). I believe
the functionality is limited, but I've never tried it. The annoyance
factor would be rather low in that case.
