Did you test a PCIe video card on chromebook_link? Looks like there are things we still need to do to support VGA rom on x86. In the bridge control (offset 0x3e) register of the PCI bridge, there is a VGA enable bit which currently U-Boot does not configure. I believe this will stop video card from working. However, so far I even cannot read the content of the VGA rom (all returns 0xFF) after I manually enabled this VGA enable bit. Do you know what may cause this?
