With kernel 3.15 and later I got "diplay not working after suspend" again. But I find out how to work around. I had scrip on shortcut for KDE and this script made display to work. Command of script is "sleep 1; xset dpms force standby".
Can you bisect?
I guess I can't. I don't use any patches. I just use Xorg and Mesa from debian.
