What about using the version field of the accelerant_device_info struct? http://cgit.haiku-os.org/haiku/tree/headers/os/add-ons/graphics/Accelerant.h#n85

Logic: 1) Wire up the INIT_ACCELERANT http://cgit.haiku-os.org/haiku/tree/src/servers/app/drawing/interface/local/AccelerantHWInterface.cpp#n303 2) Call B_GET_ACCELERANT_DEVICE_INFO 3) Check the version field returned 4) Wire up the rest of the hooks based on API version. Here we can break off into whatever logic, classes, etc. we want. Not sure if there was some planned use to that version field though.
My gut feeling is that the version field was intended exactly for this type of situation.
