Marc? It would be nice if you could read through the code and verify the things I did.
northbridge/amd/geodelx/raminit.c:auto_size_dimm() checks for the mathematically impossible condition of a value being above and below the specified range at the same time. Change it to check for out-of-range. arch/x86/geodelx/geodelx.c:set_delay_control() is missing a break, it will keep going and mess up DRAM timings.
