Looking at the two boot logs, the PCI resources allocated are very 
different. My big worry is about the reported differences on the IRQs in 
use. I'm not sure what more help I can be. I doubt that the missing CPU 
is affecting things too much, I just think that this board support code 
simply needs fixing. It would be helpful if anyone knew of any previous 
revision where it used to work?

Did you try Carl-Daniel's suggestion of booting with 2GB or less?
