You could take the route Borderlands took.
All Steam Store purchases of Borderlands include support for Steam achievements; an element of Steamworks.
However, retail purchases of Borderlands include no support for Steam and no achievements - not even in-game achievements a la Mass Effect 2.
That way, Steam-activated and Steam-purchased copies of Amnesia will provide the Steamworks facilities to people who want them, such as achievements, cloud-based syncing for your savegames and leaderboards to name a few.
