I think it's
a issue about lvds setting in VGA rom.
You can get the vbios from Intel's web
site, and you need to modify it to fit your screen.
8086/27ae 8086/27a2 just different
ID,because your have let the VGA rom run, so it doesn't matter
:-)
It should be easier to grab the vbios from the existing BIOS.
According to the logs that were attached, at least coreboot did not
run the vbios at all.
