also, they seem to do it quite wrong way. i.e. much simpler would be to 
just implement regular, open driver , and implement additional crypto
mechanism in chipset itself, allowing to use simple userspace program
sending certified keys allowing GPU to operate.
if key is not available and device/driver not paid/registered, then
GPU would simply lock itself , similiar to pre-paid designs from
company whose name should not be spoken aloud.

also certain functionality could be ordered with same chip structure,
i.e. framebuffer, unaccelerated 2d, accel 2d, 3d, etc.
with user buying proper 'entry level' pre-paid code set from manufacturer.

this would provide quite same functionality (profit), without impacting
open-source projects like Xorg with unnessesary complications.
