I have attached a boot log. The ethernet and IP addresses have been 
modified, but everything else is correct.

I checked all the dts entries marked by /* Filled in by zImage */ by 
checking /proc/device-tree and they all match what is printed after the 
log message "Uncompressing Kernel Image ... OK".

FYI: It is a 533MHz PPC but the HW guys read the spec wrong and are 
running the system clock at 66.0MHz rather than 66.6MHz, so the 528MHz 
value is correct.

Cheers,
    Sean
