Good point. But shouldn't "make i386_defconfig" and "make
x86_64_defconfig" do that?

They *don't*, but I think that's just a bug:

[dwmw2@i7 iommu-2.6]$ make V=1 i386_defconfig
make -f scripts/Makefile.build obj=scripts/basic
rm -f .tmp_quiet_recordmcount
mkdir -p include/linux include/config
make -f scripts/Makefile.build obj=scripts/kconfig i386_defconfig
scripts/kconfig/conf --defconfig=arch/x86/configs/i386_defconfig Kconfig
gr#
# configuration written to .config
#
[dwmw2@i7 iommu-2.6]$ grep defconfig .config
CONFIG_ARCH_DEFCONFIG="arch/x86/configs/x86_64_defconfig"
