[GMA965] Blank screen when GDM starts

[Andrew King]

When cold booting Jaunty, gdm starts with a blank screen - I can login (by guesswork), but screen stays blank after login.
The screen also stays blank when switching to a console (ctrl-alt-f1).

booting without splash fixes the problem (not sure if this should be in usplash instead)

uname -r
2.6.28-7-generic

usplash:
  Installed: 0.5.28

xserver-xorg-video-intel:
  Installed: 2:2.6.1-1ubuntu1

/etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=9.04
DISTRIB_CODENAME=jaunty
DISTRIB_DESCRIPTION="Ubuntu jaunty (development branch)"

I've attached results for intel_reg_dumper for working & not working cases

Cheers
Andrew
