Dear coreboot folks,
following up on , could you please test latest Linux kernels (3.12,
3.13, 3.14, 3.15) on Intel based laptops and check if the Intel driver
is able to initialize the IGD  without a Video BIOS or coreboot’s
native graphics init? If you know if that was ever possible, for example
with Linux 3.2, that’d be also interesting.
Intel made a change to their driver to rely on the VBT for
initializing the graphics device. The VBT is usually carried in the
Video BIOS so that's where that dependency comes in.
