Dudes, stripping wallpaper sucks balls when it's on plasterboard.
What would be wrong with thin plywood, over the shitty plasterboard wall and then painting?
I think ply would look weird, what's the problem with the current wall, is it disintegrating or just you've had enough fighting wall paper? You could cover with backing paper then re-wallpaper or if it's really bad get it re-plastered.
