But when the i915 driver is load (ex. via modprobe i915) my screen starts flickering with all colours.
The BIOS settings of your Alienware m14x laptop should have settings that allow you to control your VGA adapters.
I think the most straight-forward approach is to try to disable the Nvidia card from BIOS. This way you'll know for sure that Intel is used. So you'll focus on getting it to work nice.
