I think when you see this error the following happens:

You are mentioning some device in the tree description which can not be
found in the real system, so LinuxBIOS assumes there is something wrong
with your bios image and refuses to continue.

The first thing that looks suspicious is the CK804. LinuxBIOS probably
finds the NForce5 instead of the expected NForce4 and pegs out.

Please also check that the components are hanging off the correct
hypertransport link.

There is this funny notion in LinuxBIOS that you see 

pci 18.0 ... end 3 times, which reflects the 3 hypertransport links per

To find out which one is the correct one, you can read out the CPU's HT
config registers with factory bios, or read the mainboard schematics.
