There are other GPU add-on boards on market. You forgot about S3 and Matrox. They are still making GPUs and boards. Both of them have Linux drivers.
S3 released Linux driver for its Chrome GPUs with OpenGL and MPEG-2 hw acceleration.
Matrox still provides OpenGL, X-Video for Parhelia and Pxx cards.
These companies still releases new products and Linux drivers are maintained and updated. The GPU world is not Nvidia/AMD divided (yet).
