Hi Brice,
Now I also believe is a kernel problem, because enabling KMS and test...
with my current kernel (testing):
linux-image-2.6.32-trunk-686 2.6.32-5 fail, no LVDS in dmesg
using previous:
linux-image-2.6.30-2-686 2.6.30-8squeeze1 works! there is
mention LVDS in dmesg
using version on sid:
linux-image-2.6.32-1-686 2.6.32-6 fail,
no LVDS in dmesg
Sorry I didn't find 2.6.33-rc in debian packages, may be I am searching
wrong...
Also found a related problem in bug #560158 where mention 2.6.32-6
resolve this issue, but I try it and fail
At least using linux-image-2.6.30-2-686 it is a better solution than
disable KMS, I expect new kernel version could help us.
Just to comment, also using linux-image-2.6.30-2-686 in system with
intel 855 video card model works!

Thanks for your suggestions, first I try using Option "Enable" "true"
on KMS enable but doesn't work X still hang, also I try xrandr and
show no screens. After Googling found some pieces of information,
first in bug #555906 Julien Cristau sugest a way to enable KMS by
default (so previous versions of intel was working on UMS?) in recent
version of package (2:2.9.1-1+exp1-> 2:2.9.1-2). So my assumption is
when upgrade to 2:2.9.1-2 my system stop working because use of KMS,
right?
I found in bug #567712 information to disable KMS:
"A Disabling KMS fixes this problem (might be related to [1]), just
comment out
the line in /etc/modprobe.d/i915-kms.conf
options i915 modeset=0"
So I disable KMS on my system and Now it works! and xrandr detects
fine all my screens
So the problem seems to be in the kernel (that's where KMS detects
monitors) so I am reassigning this bug to linux-2.6. Does dmesg say
anything about LVDS when you reenable KMS ? Can you try 2.6.33-rc ?
