You're confusing your kernel graphics driver for the Xorg graphics
driver. They're not the same thing and you need both:
* Kernel graphics driver = i915 (there is no other option and if you disable
it

I was not very accurate... in fact you are right the flickering is in the old
driver 'intel'
i set i915
Section "Device"
Identifier "Card0"
#Driver "i915"
BusID
