Perhaps the merge of the static and dynamic trees gets tripped up by whats in the Config.lb?
That is what it looks like. The static 12.[123] appears to be on a child bus of 12.0 which is nonsense in this case.
Thats what I was thinking but I wasn't quite sure enough what the "right" way should look like.
See my other message on the properly indented version of Config.lb It appears we have structures that just aren't closed properly.
Did you miss the end after pci 9.0 here?
chip drivers/pci/onboard device pci 9.0 on end register "rom_address" = "0xfffc0000" end
