Kconfig, but I have same device tree in both Config.lb and
devicetree.cb. Just in case you're wondering, the results are exactly
same even if I don't have the VGA device defined in the device trees,
just without the extra debug output (meaning just "PCI: 01:00.0, bad id

There's discussion on just this debug message/issue on the v3 at the
http://firstname.lastname@example.org/msg04745.html; which I
believe you're well familiar with. Anyway, what that debug message
really means is the device appears in the static device tree
(devicetree.cb) but has an undefined vendor & device id. In this case,
they're 0xffffffff which suggests the bridge isn't really functioning. I
can't spot any relevant differences from the factory BIOS Northbridge
registers, though. The EPIA-M code is very old and the CLE266
Northbridge code has only ever been used with it, so there might be some
gotcha's with that.
