From an engineering perspective, a front rack that attaches via eyelets and the crown is going to offer zero stiffening of your fork, regardless of rake. The stiffness of a 4130 cro-mo rack attached at those three points will not add any significant rigidity to the front end of your bike.
Any hollow tubed rack can be drilled at the stanchions to accomodate internal wiring for dyno hubs.

What problems have you had with VO products? I've been using a VO Randonneur rack and decaleur for my Berthoud frontbag for the 2009 and 2010 rando (and commuting) seasons without issue. My VO Stainless 47mm fenders have held up through almost 3000km of rando events this season, plus commuting miles; rough mileage which rattled loose the internal electronics of a Schmidt Edelux headlamp.
