Hey Florian,

any updates?

We like to get that into the Fedora kernel, as we promised
out-of-the-box multi-seat hotplug support, but the framebuffer events
are broken at the moment.

It would be nice if it would show up in -next somehow, and gets
testing, so I don't need to convince anybody at the Fedora kernel
side, that this will land upstream ...

Thanks,
Kay
