Not sure about SDL having this support, but you could just hide the 
cursor and make your own acceleratable cursor using SDL_GetMouseState 
and SDL_GetRelativeMouseState.

Draw the cursor at position given by SDL_GetMouseState, and use
SDL_GetRelativeMouseState to figure out your acceleration effect.
