My ruby dynamic WMS server MapScript code calls setParameters() instead of loadparams(), so this seems reasonable.

	map = "MAP .... END" # shortened because it doesn't matter in this example
        map = Mapscript::msLoadMapFromString(map, "/tmp")

        req = Mapscript::OWSRequest.new()
	cgi = CGI.new()
	params = cgi.params
        params.each do |k,v|
            v.each do |vv|
                req.setParameter(k, vv)
            end
        end

        Mapscript::msIO_installStdoutToBuffer()

        map.OWSDispatch(req)

        ct = Mapscript::msIO_stripStdoutBufferContentType()
        res = Mapscript::msIO_getStdoutBufferBytes()
        print "Content-type: #{ct}\n\n"
        print res
