Anyone that owned a pre-05 boxxer knew how much those things sucked, they pretty much got worse every year you went back. Poor tolerances, easy-strip threads, overly tight fit on the stanchions/steerer, poor clamping system, horrid design on drop crown that hits frames, and I think at some stage (00-02) to top it all off they broke very easily too.
Kiss the new 06+ crowns. They fixed every single one of those problems, topped it off with neat anodizing, and at the end of the day they're relatively light anyway.
And seriously, if you think you need a lighter fork than an 06+ boxxer WC, then words like "wanker" come to mind. And yeah, that's coming from a hardcore weightweenie.
