AFAIK GeoTiffs are just regular TIFFs with additional data about coordinates and projection. In other words, any tool that can display TIFFs can display GeoTIFFs. It only gets interesting when you want to do something with the geo metadata. I've used gdalinfo to get at the metadata to stitch together bundles of GeoTIFFs using image-magick & GD. If you need to convert to different projections you may need something more specialized. update: see also the rest of the GDAL site for command line tools that handle and convert all kinds of geospatial file formats.
