I've installed that version of the `doc-view-mode' support in
the emacs-w3m CVS trunk.

Now the variable name is `w3m-doc-view-content-types'.

I tried this way too, but reached to the conclusion that it is
hard to implement a convenient way to switch `doc-view-mode' and
the external viewers.

It can be done by modifying the `w3m-local-find-file-regexps'
variable into the following for example:

(setq w3m-local-find-file-regexps
      '(nil . "\\.\\(?:[sx]?html?\\|dvi\\|ps\\|pdf\\)\\'"))
