[EN] [Solved] Kernel on Boot Captures Video Late

.. At least IMHO
.. This is just to do with Visual Preference, nothing else.

I noted by examining /var/log/kernel.log in both wheezy and sid (Siduction) that video display of the Computers Video card comes later in Sid and earlier in Wheezy.
 So, we say "So What"..

 What I don't prefer is  watching a 640X480 screen to about line 1840 in the Siduction boot but only to about line 600 in the Wheezy boot. I say about as it is moving pretty fast.
After those points in each I am presented with 1366x768 ..

So, I am looking to a way to improve the situation.

Because the Siduction kernel activates the higher resolution Video card later the boot appears more visually as a 1980 MSDos boot screen.
Rather then the High Tech kernel that it is....
 So yeah, not very important.

 Again this is an Aesthetic, simply a visual and does not impair the Kernel or Desktop in any way.

 I am thinking that the differences may have to do with this line

Jan 28 17:44:36 siductionbox kernel: [    7.780979] i915 0000:00:02.0: setting latency timer to 64

 Which may refer to the i915 running via a 64 bit kernel..
If that is the issue then maybe this is a partial explanation.

 My  Arch, Wheezy and Slackware (all 32 bit) boots all present the higher resolution almost immediately on the same machine. While the Gentoo 64 bit boots to high resolution instantly.
None of this may be of any help. Just another observation.

 IN the End perhaps this is out of Siduction's control being handed down from Debian Unstable..
  Ideas and observations of your own in comparision Welcomed.

i915 modeset=1

in /etc/initramfs-tools/modules

and do

update-initramfs -u

Followed your instructions and have rebooted a number of times.
Seems some improvement I only have 1 page of 640x480 text rather then 2 pages of same.
Thank You for the tip. Getting the i915 to be added sooner to the initramfs process.
  Here is something to ponder though.
 I checked again and I was mistaken I am running the 686 kernel..sorry for error.
My brother has Siduction 12.2 686 installed in the Same Lenovo Thinkpad SL410.
Also same hardware running i915 video module.
Hardware the same with revision exception but the revision change does not seem to account for what we are seeing.
Here is the Video hardware Mine 1st His 2nd
Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09)
..Note his is a (rev 09)

 His boots shows only a few lines at 640x480 and jumps right to 1366x768.
So I am stumped. We should get the same initramfs boot results.

We installed within 1 week and have all out updates to date.
 The only difference is I downloaded and installed the Xfce iso
and He downloaded the KDE iso. That should not account for the differences we see.
Just attempting to give you a complete picture.

 Any further thoughts?

Today I booted the 12.2 LiveCD and initramfs loads the kernel with only a few lines in 640x480 resolution as expected.
  What I can't determine is Why? Once installed on my machine does the 640x480 resolution appear for so many lines...
 Any Ideas?
