Maybe it actually prefers -hsync. Not sure why it would only have a problem on one encoder however. Does the hard-coded mode also work on the other (previously working) DVI port? FWIW, the 1920x1200 monitor I (Dell LCD), has the same preferred modeline in it's edid, however, it works fine on either DVI port on my RV730 card.
