Anoter option would be to do that :

gdal_translate -of VRT tif_with_mask_band.tif out.vrt -b 1 -b 2 -b 3 -b mask

This will turn a RGB+mask_band into a virtual RGBA

Provided that GeoServer can read VRT through GDAL. But I'm a bit surprised to 
see that only just a few GDAL formats are listed in 
http://docs.geoserver.org/stable/en/user/data/raster/gdal.html . Not sure why 
it is a limited list.
