OK, I think I know what is going on here. Here is a dump of my smbus  
with the legacy bios.

SPD would show up at 0x50 or 0x51 right? It doesn't appear there is  
SPD on the on-board memory.I only show items at 0x2d (sensor) and 0x69  
(clock chip).

So where do you think I should go from here? I could set up a *.c file  
in the mainboard directory to call a function to manually set the  
correct settings for socket2 (I know what the settings are supposed to  
be) after raminit.c dynamicly configures the register but before the  
sdram_enable function is called. It should be fairly simple to do and  
call from auto.c. What do you think?
