Bug#438650: xserver-xorg-video-intel: fails to start (No valid modes)

It means that your graphic chipset has an VGA output with no monitor
connected to it. Note that some machine have such an output without any
physical port connected to it.

I am not sure which outputs your i845 chipset has. If it's a notebook,
it should have LVDS for the internal panel, VGA for the external port,
and maybe TV for the external S-video port. But there's nothing about
LVDS in your log. If it were sending the picture to the wrong output, I
think the server would not fail to start, it would start and give you a
black screen.
Did you ever try an earlier xserver-xorg-video-intel driver? For
instance 2.1.0 currently in testing or the former 2.0.0 packages? i845
support was support to be fixed at some point (near 2:2.0.0-6), I am
trying to see whether it has been broken again in 2.1.1, or just never
worked for you.
I will probably end up forwarding this bug upstream anyway. To do so,
I'll need the Xorg.0.log with Option "ModeDebug" "yes" as you initially
had, but without all the other non-trivial options:
* drop the ServerFlags, Files and Module sections
* replace the "Screen" line with 'Screen "Screen0"' in ServerLayout
* drop the ModeLine, PreferredMode, HorizSync and VertRefresh lines in
Monitor
* drop NoAccel in Device
* drop DefaultFbBPP in Screen.
A regular xorg.conf then :)
