I've applied this patch after applying Uwe's patch

His patch modified the following files:
Index: src/southbridge/intel/i82371eb/Config.lb
Index: src/southbridge/intel/i82371eb/i82371eb.c
Index: src/southbridge/intel/i82371eb/i82371eb.h
Index: src/southbridge/intel/i82371eb/i82371eb_smbus.c
Index: src/mainboard/tyan/s1846/Config.lb
Index: src/mainboard/tyan/s1846/auto.c
Index: targets/tyan/s1846/Config.lb

But left raminint.c untouched.

I've only viewed the error messages.  I'll research them a little later.

Uwe, from what I've read concerning the i440BX memory initialization
docs, SPD is *required* to initialize memory.  This patch is needed
isn't it?  Or have we verified writing to memory is successful?  I'm
puzzled here.  (or is memory init and activating SPD two seperate things
