gpu screen infrastructure patches

[Michal Suchanek]

  Hello,

what should be hotpuggable with these?

Are all GPUs hotpugged on start with the AutoAddGPU enabled?

Or can I plug multiple cards, disable some in /sys and have them
hotplugged by X when I re-enable them?

I am not sure actually plugging cards is a good idea. PCIe is
technically designed for hotplug but that does not mean all physical
embodiments are actually hotpluggable, does it?

Thanks

Michal
