Unfortunately there isn't an option for achieving what you want.  As a
brute-force workaround you could hook into the function checking for
style options before the viewer is called and temporarily remove all
PSTricks-related styles.  This could be done with the following piece
of advice:

(defadvice TeX-output-style-check (around TeX-output-style-check-advice
                                          activate)
  "Temporarily remove PSTricks-related options in TeX Source Specials mode."
  (let (removed-styles)
    (when TeX-source-specials-mode
      (dolist (elt TeX-active-styles)
        (when (string-match "\\`pst\\(ricks\\|-.+\\)\\'" elt)
          (push elt removed-styles)
          (setq TeX-active-styles (delete elt TeX-active-styles)))))
    ad-do-it
    (nconc TeX-active-styles removed-styles)))

Please note that this involves fiddling with internals of AUCTeX's
style system and is not guaranteed to work in all future versions of
AUCTeX.  Maybe not even in current versions.  But I am confident that
it does. (c;
