And with KMS, the architecture is still that most of the video work is done in userspace. The kernel manages memory (both graphics card memory, if any, and shared system memory), dispatches command streams from userspace to the GPU in a safe fashion (stopping apps disrupting each other or accessing each other's memory space), handles interrupts, does modesetting, and resets the GPU when userspace apps crash it.

Everything else (all the complex command stream creation) is done in userspace still.
