You can accomplish what you want with GRASS, but I am not
sure of all the details.  An alternative is to warp the image with

  gdalwarp -t_srs WGS84 in_coverage/hdr.adf out.tif

Once again gdalwarp isn't part of PROJ.4 proper, but you
can find it in normal GDAL/OGR builds such as FWTools.

Good luck,
