I would have navigated the menus of "coreinfo" coreboot's secondary payload, to see if there's anything interesting related to the PCI devices. Also: Please could you plug in a discrete GPU (preferably AMD) into the PCI Express slot, and check if it is working?
I have an old X1050 just works perfect, if the setting are not forcing the iGPU which works fine as well. Host and PCI bridges (below) seems to missing from the list. I checked with both coreinfo and Linux OS. So these are available on the factory image. External NIC also working fine.

As far as I remember I had the same problem before Bolton and Hudson has been merged, but I'll have a look later.
