4chan and w3m

I'm moving from Firefox to w3m. I use the 4chan extension in firefox, and have found it very useful and would like to use something like that in w3m. Does such a thing exist, and if not, how would I go about making it? It mostly is just a set of links, but I wouldn't know where to start.

/prog/ doesn't even work in w3m because 4chan's content types are broken. w3m sends an Accept header of
text/html, text/*;q=0.5, image/*. Apache notices /read/prog/1205019829/1- is in fact of type application/x-httpd-php, and sends a 406 Not Acceptable error.
