The problem is that Xorg hasn't registered the igfx as the boot-vga device and so is looking for a primary display and fails (it loads the -intel as a secondary GPU only screen).

What is the value in '/sys/devices/pci0000:00/0000:00:02.0/boot_vga' ?

You can manually specify:
Section "Device"
  Identifier "Device0"
  Driver "intel"
EndSection
in /etc/X11/xorg.conf.d/intel.conf to workaround the issue.
