Last time I was there (about 2 months ago) the KUL lounge had a large sheet at the entrance showing a table where you could check whether access for you and/or guest was permitted simply by lining up your OW / MPC status and the class you were travelling that day. Very handy, although the lounge itself is nothing to write home about. The hot food was a handful of satay sticks, a few dry sandwiches and very little else other than some cheap spirits and a bunch of - admittedly comfortable - chairs. The staff there, although friendly, had the annoying habit of sitting on the counter table in reception and chatting to each other.
