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.
It's not a horrible move.
What it means is that coreboot should grow a data model (have we
heard that before?) to expose the relevant data to the graphics
driver.
For compatibility it might be wise to use the legacy VBT format.
Perhaps we can do something clever with coreboot tables, like putting
the VBT into a table entry located in low memory.
