I don't know the class internals "by heart", but I would think that it's
not a big problem to do this. Since \title has only a single argument,
it's probably as simple as
\let\origtitle\title
\renewcommand{\title}[1]{%
% stuff needed for the DVIPS specials
\origtitle{#1}
}

If you want to do it without altering dvips, you would have to alter the
PS file. This isn't trivial, but it may be doable if you know
PostScript.

I don't know of any document dedicated to explain the dvi format, but if
you take tex.web (Knuth's original source file) either from the
tetex-bin sources (in texk/web2c) or from
http://svn.debian.org/wsvn/pkg-tetex/tetex-bin/trunk/texk/web2c/tex.web?op=file&rev=0&sc=0,
you can run it through weave and tex and get a document with a chapter
called "Device-independent file format". If you use pdftex, it even has
a Bookmarks pane on the left, so you can easily find it. As for dvips
itself, I fear there's nothing but the source and the (sometimes
outdated) texinfo manual.
