screens fades away with i915 module

OK, first I have a CR48 and I am not new to linux. I know with Arch being a "bleeding edge" system sometimes things wont work right all the time, but I have tried for over a week trying to track down a problem with my i915 module.

My screen will get lines before finally fading to a grey.
It will fade on lid switch and on suspend and hibernate.
The issue does not happen at the grub boot screen.
i915 is loaded with initram and the issue happens before X11 loaded.
I get no errors in my logs either... making it even more frustrating.

So I definitively tracked it to the i915 module, I tried several different configurations and still no luck.
Only thing I an think of is to load it differently, since the issue happens before X, changing xorg settings wont help.
Anybody have any insight? Would be very appreciated, and hopefully I haven't been chasing another bug... =/

I cannot speak as to why it is happening, but the "Fade to Grey" is indicative that the video hardware has stopped sending data to and/or has stopped clocking the LCD. Without updates, the LCD shutters eventually decay to their relaxed position. Just FYI.

also, it happens randomly on lid which makes it more confusing, except for suspend/hibernate of course (consistent). maybe some events are being triggered before others are ready?

xf86-video-intel-git from aur didn't help;
Using vbetool to turn dpms on/off seems to be working for the time being, the result gives me a delay when resuming but for stability, who cares. But only downfall is I have a small window between grub and when acpid is loaded that my issue could reoccur, again big woop.;
I have a strong feeling this is another bug so this is the best workaround I got.
