The via drm still needs command verification checks of the AGP ring-buffer,
Well via isn't shipped as it still (??) has security problems, or if they

the 3D driver to be ported to use the ring-buffer and finally the DDX to export the
MMIO area as read-only instead of read-write. From what I know that should take care of the
security problems.
Last time I talked to Erdi Chen he was short of time of doing the command verification and 3D driver updates.
One option is to do command verification for 2D commands only, and tighten up the DDX. In this way the DRM could go into the kernel and be usable with XvMC. OpenGL possibly as root, until someone has the time to fix up the 3D driver and implement a full command verification.
