We only need one X.org 2D and one Mesa 3D driver for each card, but DRI
supports as many rendering APIs as you like, including XvMC which offers
accelerated video decode on top of DRI as well.

So, the answer is that yes, at this point, we have only the two Intel
integrated graphics drivers using GEM, but also no, the interface can
support as many drivers as you want.

I hope that GEM will encourage more graphics API research as it allows
multiple user-space APIs to talk to the same underlying hardware
resources.
