I didn't do anything special, the "make menuconfig" step grabbed
the config file to use as defaults. Just to verify, I did
"make menuconfig" again (on a clean build dir) followed by a
"make oldconfig". The resulting .config file (from both steps)
is identical to /boot/config-2.6.8-11-em64t-p4-smp.

Now compiling with the V=1 option ...
I think I see the problem ...
Here is the gcc command line. Note that the extra include path
added by the Makefile in arch/x86_64/pci has a space between the
-I and the arch/i386/pci.
gcc -Wp,-MD,arch/x86_64/pci/.mmconfig.o.d -nostdinc -iwithprefix include -D__KERNEL__ -Iinclude -Iinclude2 -I/usr/src/gm/kernel-source-2.6.8.work/include -I/usr/src/gm/kernel-source-2.6.8.work/arch/x86_64/pci -Iarch/x86_64/pci -Wall -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -march=nocona -mno-red-zone -mcmodel=kernel -pipe -fno-reorder-blocks -Wno-sign-compare -fno-asynchronous-unwind-tables -O2 -fomit-frame-pointer -I/usr/src/gm/kernel-source-2.6.8.work/ -I arch/i386/pci -DKBUILD_BASENAME=mmconfig -DKBUILD_MODNAME=mmconfig -c -o arch/x86_64/pci/.tmp_mmconfig.o /usr/src/gm/kernel-source-2.6.8.work/arch/x86_64/pci/mmconfig.c
I'll try changing arch/x86_64/pci/Makefile to remove that space ... Works!
Here is the patch I applied to the Makefile:

How can it be that the shipped kernel source is not compilable?
Makes me wonder what else is different.
Now I will go on to the make-kpkg step and then try booting on
this kernel.
