Have you tried re-positioning the straps on your Camelbak? I can ride in my Platypus as long as I loosen the straps so that it rides low on my back. If I leave them in "hiking" position, they really hurt my back on the bike. Also, my packs are the kind that have the waist strap as well as the sternum strap - it does seem that some of the Camelbak brand packs ride very high.
A really dorky solution would be to stow a hydration pack in a handlebar bag. Better than running out of water. You'd probably be limited in the amount you could carry up there, though, just because of weight considerations.
