What does your OUTPUTFORMAT block look like? We use this one (below) 
with transparency all the time. In particular, the TRANSPARENT had to be 
set to "on" for our case.

OUTPUTFORMAT
   NAME "png"
   MIMETYPE "image/png"
   DRIVER "AGG/PNG"
   EXTENSION "png"
   IMAGEMODE RGBA
   TRANSPARENT on
   FORMATOPTION "INTERLACE=OFF"
END
