When you are submitting this patch ;-), you might want to add a note 
that this is reading from the standard configuration information from 
the I2C EEPROM on a DIMM memory module.  This command is not useful for 
built-in SDRAM memories (i.e. soldered to the motherboard).

I suspect that applies to Frank and the SDRAM configuration read command 
is not useful for him.  In general, if you have DIMM memory modules, you 
probably have I2C enabled in order to configure them.  Conversely, if 
you don't have I2C, you probably don't have DIMM memory modules and the 
command is useless.  The third case is that you have DIMM memory modules 
but are not using the I2C configuration information out of them... in 
that case you should be adding I2C and the automatic configuration.
