I can think of one way that might work:

Hash that part of the cookie in addition to the URL and host, something like:

	vcl_hash {
		if (req.http.cookie) {
			set req.hash += regsub(
			    req.http.cookie, 
			    ".*LOCALIZER_LANGUAGE=\"(..)\".*",
			    "$1");
		}
	}

(If this work, please take a moment to add it to our FAQ!)
