I'm not sure I understand what you want to do. It seems you'll get a
redirect loop. But anyway, try this (untested):

map $arg_arg$arg_language $redirect {
default 0;
nginxru 1;
## Add as many lines as arg_arg and language combinations needed...
}

location = /page.php {
error_page 418 =200 /nginx;
if ($redirect) {
return 418;
}
## FCGI content handler here...
}


location = /nginx {
if ($status != 200) {
return 302 /page.php?$query_string;
}
try_files /page.php?$query_string =404;
}
