Auto BMT for Non-M3 AML in 1st Remission in Pts </=60y of Age Using Busulfan/FTBI & VP16 as a Prep R

RATIONALE: Giving chemotherapy before an autologous stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. After treatment, stem cells are collected from the patient's blood and/or bone marrow and stored. More chemotherapy and radiation therapy is given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy and radiation therapy. Giving aldesleukin after transplant may help keep cancer cells from coming back after transplant. PURPOSE: This phase II trial is studying the side effects and how well giving busulfan and etoposide together with total-body irradiation followed by autologous stem cell transplant and aldesleukin works in treating patients with acute myeloid leukemia in first remission.
