bMouseAcceleration
It has been verified that this setting is completely placebo. The game does not recognize it at all. All versions from 1.1.21.0 through the present have been examined and show no evidence of this setting ever existing. It does not appear in game-generated INIs or in Launcher presets. Its origin appears to be from the SkyrimPrefs.ini file that resides inside the extra Skyrim directory inside the main Skyrim directory, where it is set to 1. It is likely this is a leftover setting from development that was taken out prior to release, or at least immediately following release (version 1.1.21.0 was released the same day the game was released). It supposedly toggled the ability of the mouse to accelerate while moving.
