I have no actual experience with either my 'blad/Zeiss lenses on a current digital back or digital Rodenstock, Schneider or other lenses on film. From what I read the digital lens corrections have much more to do with APO quality and focusing all the color at the same point than dumbed down resolution. They're also optimized for use at larger apertures then those traditionally used in large format photography. In the end - I think it comes down to "systems." Lens design (on the high end) is changing for digital. and older lens designs "may not" perform well on digital sensors. As we're on the transition team we imagine we can blend the two approaches film systems with digital systems. I expect the next 3 to 5 years will prove that the two systems don't mix up so very well. Yet I'd expect a high resolution APO digital lens which performs up to spec on a high resolution digital back will perform better on film than a dated, but fine performing film lens, will on a high resolution sensor. And I'm more than willing to be "proven" wrong.
