Federico, I have here also suggestion for you. You should try to run only one DDR memory stick, and then record the memory values (since I see from your logs that they are identical for both memories/DDRs), and then to try to hard-code them for both sticks, altogether avoiding raminit.c setup, and see if this improves your situation?!
Hi Zoran and others,
I finally flashed again coreboot after trying the Lenovo BIOS. I used the decode-dimms util to dump RAM info while on the Lenovo BIOS with both RAM sticks, and run the same program on the coreboot BIOS with just one stick.
Sadly the output on coreboot is the same of the output on Lenovo BIOS so no info gained by this.
I will attach the output from the Lenovo BIOS in case it turns out useful.
The next step I will try will be to modify raminit.c of Nehalem to accept hardcoded frequency as SandyBridge does, hoping that this will be a temporary fix to get the two DIMMs working.

this is pretty much expected. `decode-dimms` reads the SPD ROM on the DIMM. It's just static data about the timings that the DIMM supports.
You can read the current configuration of the memory controller with `inteltool -m` (you'll find it in util/inteltool/ of the coreboot tree).
Hope that helps, Nico
