Bug in xf86-video-intel

[Henri-Pierre Charles]

Hello, I think I've found a bug in this driver :

FreeBSD 8 with xf86-video-intel-2.7.1 on an atom
based machine with "<Intel 82945G (945G GMCH) SVGA controller>"

Machine description (in french) http://www.ldlc.com/fiche/PB00089880.html

Symptom : Freeze for 2/3 mn at
  - xdm start
  - session start
  - graphic output using shm (xv, qiv, etc)

Tried :
  - use vesa mode : it works but I can't use the 1910x1080 resolution : unusable
  - downgrade xf86-video-intel to 2.6 branch : same symptom
  - disable shm with
 Section "Extensions"
      Option "MIT-SHM" "Disable"
 EndSection
 in /etc/X11/xorg.conf : same symptom
  - disable acpi (hint.acpi.0.disabled="1" in /boot/loader.conf) : it works but
I can't use the multi thread capability of my Atom230 which is a pity on this
machine.

I've add a comment on http://bugs.freedesktop.org/show_bug.cgi?id=24789

Any hints to try from BSD specialists ?
