Can a court of appeals hear an appeal from a final decision of the bankruptcy court?

Section 158 grants courts of appeals jurisdiction to hear appeals from "final decisions ... entered under subsections (a) and (b) of [Section 158]." Subsections (a) and (b), however, concern only appeals heard by district courts from bankruptcy courts. Because the district court in the instant matter was exercising original jurisdiction under Section 157(d), we do not have appellate jurisdiction under Section 158. See United States v. Nicolet, Inc., 857 F.2d 202, 204 (3d Cir.1988).
