It's always good to check targets/vendor/board/build/fallback/ldoptions to
see what's really being used.

Great.  I think we're getting to where we should add your board to the
tree.  Then we can see the device tree too.

It device 0:02.3 isn't getting a driver.  1:06.0 is not found.

PCI: 08:01.0 Hypertransport link capability not foundPCI: pci_scan_bus for
bus 08

That doesn't look good.

PCI: Left over static devices:
PCI: 08:01.0
PCI: 08:01.1
PCI: 08:02.0

VGA: PCI: 00:18.0 (aka node 0) link 2 has VGA device

That doesn't look right.  I would think it's on link 0.  I don't know why
that's set wrong, but it would explain why it's not working.
