I wouldn't know how to distinguish xemacs-mule and xemacs-non-mule,
but Chaskiel Grundman already gave the answer: The latter is lacking
modify-coding-system-alist. So how about

; Exclude xemacs-non-mule, which isn't suitable for i18n work.
(if (fboundp 'modify-coding-system-alist)
  (progn
    ; Determine the coding system according to the rules specific for PO
    ; files.
    (modify-coding-system-alist 'file "\\.po\\'\\|\\.po\\."
                                'po-find-file-coding-system)
    (autoload 'po-find-file-coding-system "po-mode")))
