Following your suggestion, I add these

(add-hook 'dired-before-readin-hook 'sdl:test)
(defun sdl:test ()
  (let ((path default-directory))
      (when (file-remote-p path)
          (set-buffer (cdr (assoc path dired-buffers)))
          (set (make-local-variable 'dired-listing-switches) "-al"))))

I can verify dired-listing-switches has been changed to "-al" but I am
still getting the same error:

,----
| /ssh:cssa:/users/home/cssa-cam/web/cookbook:
| ls: illegal option -- v
| usage: ls [-ABCFGHILPRSTUWZabcdfghiklmnopqrstuwx1] [file ...]
`----

Although,

,----
| dired-listing-switches is a variable defined in `dired.el'.
| Its value is "-al"
| Local in buffer cookbook; global value is "-ahvl"
`----

Ideas?
