I actually have a related similar Xorg.0.log, and since alupu's
attachments still didn't show the kms related line which I assume he
was initially talking about, I'm attaching this log here.

I don't know if it helps much, the situation I have is that I'm trying
to remote debug / help a co-worker get his new Dell Latitude E6510
running (the terrible bug 29278 ie. black screen), but I've been
unsuccessful. I'm not sure if the lack of kernel modesetting problem
mentioned in the Xorg.0.log is some kind of newbie problem that I'm
just not realizing since I don't have the laptop myself in my hands.
The i915 module _is_ loaded, and there is nothing special in dmesg
(and only kernel parameters are quiet splash). However according to
him the screen (now not blank black with the custom kernel) seemed
normal 80x25 ie. somehow not mode-setting kind of screen. Or it might
be possibly because of the custom kernel build instead of Ubuntu
build, unless i915 should always select some higher native resolution
which would automatically result in a smaller font. Nevertheless there
is no log indication of kms failing to initialize or so. I used
Ubuntu's 2.6.37 kernel config as the basis, so CONFIG_DRM_I915=m and
CONFIG_DRM_I915_KMS=y are there.

The kernel in use is edp-fixes-2 and I also gave him drm-intel-fixes
one with the same result. Only vesa driver works for him for now.
