I think I've hit basically the same problem Oleksij is reporting (blank eDP) when using the ASUS UX31E with an external HDMI monitor and leaving it plugged in while booting (https://bugzilla.redhat.com/show_bug.cgi?id=844985).

Aside from the fact Oleksij uses VGA and I use HDMI, it otherwise seems to be the same issue.

I ended up finding this bug report because one of the patches attached to this bug while searching for the "bad panel power sequencing delays, disabling panel" error message I found in dmesg.

I'm also still seeing the problem Bryce described way back in the original bug report: if I use Fn+F8 to disable the internal LCD, it doesn't come back unless I do a mode change on the internal monitor. That seems to be a very different problem though, as in that case eDP1 still shows up in the xrandr output.
