I'm gonna revive this one. On my Broadwell laptop it works as expected IF I
have i915kms (drm-stable-kmod package) loaded.

However, when suspending from console (with no drm driver loaded), the screen
does not come back on after resume. The system is fully operational though. 

In resumed state with black screen (from ssh):

startx with scfb driver won't make the screen come on.

kldload i915kms will make the screen come on.

UEFI amd64 boot with kernel version r333603
