The console output is really unhelpful if the DDR3 init finds no usable
ram. I suspect that is your problem, but you'll want to turn on additional
debug output (sorry, you caught me at a bad time, I should look up the
config option for you). If indeed it isn't able to init your DDR3, the
output would look like this.

Hope that helps.
