I use the following, mostly stolen from someone else...

(defvar find-file-root-method "multi/sudo:"
  "*The Tramp method to use for opening files with `find-file-root'.")
(defvar find-file-root-user   "root"
  "*The user to su to when opening files with `find-file-root'.")
(defvar find-file-root-host   "localhost"
  "*The host to use when opening files with `find-file-root'.")

(defun find-file-root (file)
  "Open FILE sued to a different user..
Uses the method specified in `find-file-root-method' and the user from
`find-file-root-user'."
  (interactive "FFind file (as UID 0): ")
  (require 'tramp)
  (find-file (concat "/[" find-file-root-method find-file-root-user "@" 
find-file-root-host "]" file)))

(global-set-key [(control x) (control r)] 'find-file-root)
