I don't think that would be feasible. A modern graphics card is an incredibly complex beast - asynchronous queues, DMA engines, modes, interrupts, hundreds of registers. Not to mention microcode. It isn't only about poking values in registers - you also need very detailed understanding of the internal organization of the chip. And I am not even talking about the 3D stuff ... I have had the chance of seeing commercial closed source graphics drivers (under an NDA) and I had a relatively hard time figuring stuff out using the source and using whatever documentation was available (which is not always complete or entirely accurate).
