Perhaps I'm not clear on what constitutes "8-bit pseudocolored map generation". I am using the AGG/PNG driver with TRANSPARENT ON.

FWIW, here is my favorite IMAGETYPE block for generating AGG PNGs with transparency:

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

It does set transparent off, but the RGBA uses alpha blending to make transparency anyway. We love it.
