It requires 3 texture units and the VBO extension. I can probably do without the VBO requirement, but if a card doesn't support VBO it almost definitely doesn't allow 3 tex units.
3 tex units are required for proper rendering of terrain. Each layer has a separate texture, lightmap, and alpha map. My artists have been begging me for months to allow a separate lightmap and alphamap, and in a situation where backwards compatibility holds up progress, I think it is best to move on.
