pm-suspend and pm-hibernate (including resume) works on 3.16.0rc2+ without i915
module loaded

I tried again, using the following procedure, to confirm i915 as the cause of
the S4 resume problems:

* booted with parameter "i915.modeset=0 text" (to avoid lightdm startup)
* echo 0 > /sys/class/vtconsole/vtcon1/bind   (which froze the local console, I
had to continue using SSH)
* pkill alsactl
* rmmod snd_hda_intel
* rmmod i915
* sudo pm-suspend    (worked)
* resume             (worked)
* sudo pm-hibernate  (worked)
* resume             (worked, even without using the same kernel parameters)

So it seems the i915 module is actually the cause of the resume problem. Or is
it? Log (dmesg) attached.
