[LinuxBIOS] multiple devices in mainboard Config.lb

[Stephen.Kimball at bench.com]

I'm trying to write the mainboard Config.lb file to support a CK804 and an IO4 on one Opteron.  

I can write a mainboard Config.lb file that will boot the system from an IDE device, but that's only because new device table entries are created for the IDE device.  So I'm not using the static on_mainboard=1 entries.

I can write a Config.lb file to use the CK804, but incoherent.c bumps up the device numbers and northbridge.c moves the device to bus 1.  Then I get the PCI bus configured like this

If I add "device pci_domain" statements before the devices, I get this

So why does incoherent.c need to bump up the device numbers when the devices are on different busses?  There should be no device number conflicts?  No matter what I do, LinuxBIOS always creates new device table entries, because my Config.lb file has the devices on the wrong bus - 0.  The config file doesn't specify a device's bus and it doesn't assume a bus from the domain statement.  How is this suppose to work?

Attached is my Config.lb file.

Thanks for the help.
