I do not recommend to use if/rewrite in nginx as they have some
implementation issues. Nevertheless, your way is better than passing
2 requests to FastCGI.

I'm going to implement the non_existant_request_file directive to use
in similar configurations:

    location ~\.php$ {
        non_existant_request_file  @drupal;

        fastcgi_pass  ..

This directive test a request file existance before passing a request
to fastcgi/proxy.

Could someone suggest better name ?
