Oh, I only see it.  What you want to do is this, don't you?

(define-key w3m-mode-map [remap oldfun] 'newfun)

Even if `oldfun' is not a symbol, you can do it as follows:

(dolist (key (where-is-internal
	      (lookup-key w3m-mode-map "K")
	      w3m-mode-map))
  (define-key w3m-mode-map key 'your-favorite-command))

This will replace the command, that the "K" key is bound to, with
`your-favorite-command' for all the keys in `w3m-mode-map'.

grep -r '(define-key.*(lambda'

reports that many ELisp modules use it in the Emacs source. ;-)
