As Static says, you could go above your lintol but you're almost certain to come across a seam of 450:1 (sand to cement) immediately on top of it followed by the crumbly edge of clinker block. Don't hold your breath with that one then.
Hanging it from the ceiling, as suggested, is another possibiity but your missus might not care for her curtains doing a ninety-degree as they drape themselves decorously in front of the window! The little ruffly bits might not look too god either!
If it is a catnic, there won't be a gap between the plasterboard (or plaster) and the steel. If that's the case I would personally, and I stress personally, go down to the hire shop and get a Hilti gun. Tell the man at the shop what you're trying to do and he'll fix you up with the correct nails.
Don't be frightened of the Hilti, once you have the first nail in, you'll be at it like Rambo and SWMBO will view you in a completely new light. If you Hilti the batten on you can hang donkeys off it (although why you would want to do that is beyond me)

p.s. no-one has ever accused me of knowing what I'm talking about.
