full dmesg with drm debug enabled.

Hi all, 
I have an issue with a i7 3770 / q77 desktop, DVI-D monitor. (tested with linux 3.9.1)
Basically, the machine boots up in text mode but when the kernel switches to i915 driver, the screen becomes blank. It resumes only when X starts.
I've tried all the possible combination fo kernel boot parameters with no success, even applying all the hints collected thru google.
I'm quite sure that I'm doing a very stupid mistake, but I can't sort where it is, so I filed a bug here.

Attached you can find full dmesg with drm debug active (drm.debug=0xe) X kicks in approx at second 273.
Of course I can provide other data and perform other tests, just let me know.

Many thanks for any answer.

You don't load the framebuffer console driver. modprobe fbcon will give you a console.
