There's a corner case when X and the kernel know about the graphics device, but libdrm doesn't, in which case an assertion in the X driver fails and X doesn't start. Upstream libdrm has been okay for a few releases. A bug against Debian libdrm has been open for a while, but they seem to disagree about the importance, nothing has happened. In fairness, this device seems to be rare so far. I'm not really using mine any more, I put an extra graphics card in the box.
