We've recently add a new technique in DRM called 'leasing', which allows
you to create a new DRM controller for a subset of the available resources.
Cool. In your talk you even mentions multiseating.
AFAIU with this technique one doesn't get multiple /dev/dri/card* for a GPU out
of the box, so it is not possible to use unmodified modesetting driver to run
multiple X servers.
