Emacs 22 adds ".html" by default.  Though I've never tested it,
you might possibly be able to do that even with Emacs 21.4 by:

(setq-default browse-url-temp-file-name "/some/where/burl-temp.html")

Exactly.  It becomes quite useless if you save it to a file
because faces and properties are removed.

Otherwise, you can feed html content to the external browser if
you run `browse-url-of-buffer' in the buffer where an html
source is viewed.  To make emacs-w3m display an html source,
type the backslash key in the *w3m* buffer.
