I gaurentee that most of Gelato is probably supplimental software rendering replacements for features not supported on a 3d card. The package probably queries the card, finds out that the card can or can't do X feature then suppliments this feature with its own software libs. All the card probably ends up being is a polygon blitter in which the textures are precreated in software then just loaded to the card. So the software doesn't actually rasterize the poly. Not much of a big deal if it doesn't get much. I like to think of using a 3d card for real renders like the movie Star Trek I where this massive, super high tech ship has to do all its work through this primitive, 20th century Voyager spacecraft. Again, limited ram and limited features does not a good render make.
