Sometimes it will actually freeze while GDM is loading or when GDM is actually loaded.
Turning off compiz has no effect.

Used X -configure to generate an xorg.conf file. (Changes made are made to both entries of the graphics card in the xorg.conf)
AccelMethod uxa
A freeze occurred after a while into gnome.
Gnome do was using a lot of cpu, uninstalled gnome-do.
Freeze still occurs.
DRI off --> Freeze
Option "NoAccel" "True" --> Freeze
Removed all references to two screens and cards.
AccelMethod "XAA" --> Freeze
AccelMethod "EXA" --> Freeze
AccelMethod "UXA" --> (Again because I changed the config to mono screen setup) --> Freeze
DRI "False" --> Freeze
NoAccel "True" --> Freeze
"AIGLX" "Off" --> Freeze

vesa instead of intel driver --> Doesn't even load the GDM
intel driver again
PM "off" --> Freeze
"NoMTRR" --> Freeze

Well, that is all there is on the trouble shooting page, except for the bisecting.
But I must admit, that that seems a bit well difficult and time consuming.
