I think you have to find the correct decode settings for the north-
and southbridge, so that accesses to the top 4MB are decoded to the
flash chip. You need documentation. Maybe the 945 code in coreboot
implements some of this, maybe inteltool can help, but there's no
guarantee that the decode registers are the same in your chipset.
