Could be tricky. Solvents (such as acetone) that can dissolve superglue will dissolve most other plastics (superglue is a type of plastic also). With an ebony interior it could result in a "smearing" of the surface in the plastic with ugly white-ish swirls. Maybe try using an Exacto knife to slice it off and then carefully sanding the residue down.
Most likely the superglue has already damaged the surface. Like Smashalot said, once it bonds it tends to dissolve itself into the surface. You could try holding a bag of ice on it to get it loose. As with gum, some glues tend to snap when cold. Otherwise, last resort is to slice it off with a sharp x-acto knife as was suggested. Not sure polishing will be very effective afterwards though.
