Create/edit the page http://wiki.apertium.org/wiki/Dravidian_languages on the apertium wiki, making it look like http://wiki.apertium.org/wiki/Turkic_languages and http://wiki.apertium.org/wiki/Indic_languages. It should have a short background on the Dravidian languages (where they're spoken, number of speakers), a table summarising all stand-alone language packages (check in languages and incubator), and a table summarising current pairs (check in incubator, nursery, staging, and trunk). Make sure to implement stats pages correctly for all languages and pairs.  Don't worry about coverage numbers, but do count stems (see http://wiki.apertium.org/wiki/The_Right_Way_to_count_dix_stems).
