[gdal-dev] vrt removes transparent pixels?

I want to change the color palette on a gif file.  The
instructions on the wiki here:
explain how to do it:
  gdal_translate -of VRT your.tif your.vrt
  gdal_translate your.vrt your_fixedup.tif

but doing this (without editing the .vrt file) changes
transparent pixels to white.  Is there a way to use
gdal_translate to do this and also keep transparent pixels?

Or is that related to error message from gimp?
  .gif: unknown field with tag 42113 (0xa481) encountered
(gimp didn't complain about the original image)
