I don't expect Dell to change the mapping on older models to be in conflict with the printed label. But if you're a heavy user of Fn+Left/Right for Home/End, you might want to consider a different brand than Dell to succeed your XPS. Also, I don't think anyone called it a bug, it's rather an 'issue' (except the problem described with the external Dell-keyboard, which indeed sounds like a bug...)
