I'm using the same board revision too.

Strange.

This could be the case. Do you have another Kilauea board?

This is a different issue. The DDR2 autocalibration had a bug. Because of this 
some boards could boot just fine with autocalibration enabled and some not. 
This bug should be fixed now. In the latest U-Boot version autocalibration is 
enabled again for Kilauea and seems to work now. At least I didn't notice any 
problems anymore. Please give it a try and let me know if this doesn't work 
for you.

But again, this is a different issue. Not sure how to help you with the PCIe 
detection problem.
