I didn't see your forum post until now.
I believe that the old slave cemetary talked about on the ghosttowns page on Enterprise is really the black cemetery of the old town "Garfield." Garfield is listed as a seperate ghost town on this website, but it was really an off shoot of Enterprise made by the local blacks back in the day. Eventually, Garfield the town died away. Enterprise, during it's heyday, was expected to become the county seat and center of life for Volusia county. That never happened.
Anyway, if you take Lakeshore drive East, there is a road called "Garfield" that runs North off of Lakeshore. This is where the town of Garfield was.
There is an old cemetery for the town of Garfield on Panama Ct, but I don't know if it's the same "slave" cemetery ghost towns talks about.
And the local citizens are worried about growth and are fighting to preserve what little they have.
