Now, if you have a VIA graphics chip, things may be better since they recently released an [http://www.viaarena.com/default.aspx?PageID=2&Type=4 open source driver] for both 2D and 3D operations.
 
There are virtually no tutorials or datasheets for the 2D acceleration features either, but at least we have open-source code for them. Among other sources, the Xfree drivers, [http://cvs.sourceforge.net/viewcvs.py/open-beos/current/src/add-ons/accelerants/ BeOS accelerants] and [http://www.talulashawnhargreaves.demon.co.ukcom/freebe/ FreeBE/AF]. 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://pdos.csail.mit.edu/6.828/2008/readings/hardware/vgadoc/ VGADoc].
 
Anyone who wishes to put time into that kind of research is welcome to post their results here.
