Normally when you enter a file with diff3 conflict markers you should be
able to automatically activate smerge-mode (a minor mode specifically
designed for that).  Ideally, this already works completely
automatically (thanks to VC).  If it doesn't, please give us
some details (I know it doesn't always work, but I'm not sure in which
circumstances it fails, so it'll help me fix it).

In case smerge-mode is not automatically activated, you may want to add
something like the following to your .emacs:

   (defun sm-try-smerge ()
     (save-excursion
       (goto-char (point-min))
       (when (re-search-forward "^<<<<<<< " nil t)
         (smerge-mode 1))))
   (when (fboundp 'smerge-mode) (add-hook 'find-file-hooks 'sm-try-smerge t))

Now, once smerge-mode is activated, you can enter ediff with C-c ^ E
