Enable most verbose logging (8 ?) and post new logs. Also readers on the
list have currently no clue how You obtained and modified your local
copy of Coreboot.

Your posted serial log appears exactly as from the coreboot sources.
Double-check you have really changed the call to sdram_enable(),
recompiled, flashed correctly etc. 

If you are running closed-source assembly code copy-pasted and mixed
within coreboot, don't expect much assistance until you have convinced
us that at the minimum ram_check() passes without errors after
sdram_enable() :)

The following patch contains a replacement ram_check() that I consider
more reliable or thorough: http://review.coreboot.org/294
