The new Scott Genius carbon is under 5 pounds with shock, but I think it's a stupid gimicky bike. Also, it actually has 150mm travel.
I reckon Cannondale Scalpel carbon would be pretty light. It has 110mm (4.3in) travel and comes in 15.9". The Rize would be a light 5" travel frame but the smallest size is 17". Sorry, I guess I haven't helped.
