Thanks for the patch, here is the result.

initialize_cpus() is not called.

Currently I used an other Config.lb therefor the northbridge is init not 
as first.
However I will modify the Config.lb back and try it again, but I think 
the result is the nearly the same ;)

Doesn't matter. I think the best way is to init the cpu in early state 
and set the registers for L1 caching before LB does the other stuff. It 
should be much faster as now.
