There are virtually no tutorials or datasheets for the 2D acceleration features either, but at least we have open-source code for them.

They may provide enough information to reverse-engineer and figure out a model that could be used to program/port for your environment. Some older cards with only 2D acceleration might be documented by the [http://home.worldonline.dk/finth/ VGADoc].
