I'm running two external screens (one thunderbolt, one via the hdmi port) on unpatched 10.3 without any issue on my mbp... I can use the laptop display at the same time also (usually don't -- but I have to close the lid before I start X otherwise it'll stay on) ....?

Is it just your model? It;s behind my desk but it's some cheapo thunderbolt->hdmi dongle made by "neeto" apparently, works well enough..

I think 10.3 has an older version of i915, this has worked on vanilla, but 11 has already Linux 3.7 or 3.8 DRM imported which breaks with thunderbolt display, and it was fixed in drm-next-4.7 patch (which is going to land on HEAD someday, but it might not be backported to 11).
