I'm pretty sure. If I recall correctly, Nvidia's driver (nvidia_drv.o)
doesn't use DRI, but instead uses their own kind of DRI through their
kernel module.

Mark Vojkovich <mvojkovich@nvidia.com> would probably be the best person
to ask about this, since he maintains both nv_drv.o (XF86) and
nvidia_drv.o (Nvidia's driver).
