Never used kvm-kmod on x86 only with x86_64.

How do you compile it then, I only get so far:
$ make V=1
make -C /lib/modules/2.6.26-2-amd64/build M=`pwd` \
                LINUXINCLUDE="-I`pwd`/include -Iinclude \
                 \
                -Iarch/x86/include -I`pwd`/include-compat \
                -include include/linux/autoconf.h \
                -include `pwd`/x86/external-module-compat.h " \
                "$@"
make[1]: Entering directory `/usr/src/linux-headers-2.6.26-2-amd64'
test -e include/linux/autoconf.h -a -e include/config/auto.conf || (        \
        echo;                                                           \
        echo "  ERROR: Kernel configuration is invalid.";               \
        echo "         include/linux/autoconf.h or
include/config/auto.conf are missing.";   \
        echo "         Run 'make oldconfig && make prepare' on kernel
src to fix it.";       \
        echo;                                                           \
        /bin/false)
mkdir -p /tmp/kvm-kmod/.tmp_versions ; rm -f /tmp/kvm-kmod/.tmp_versions/*
make -f scripts/Makefile.build obj=/tmp/kvm-kmod
make -f scripts/Makefile.build obj=/tmp/kvm-kmod/x86

What are you building, exactly? Did you load the tarball from sourceforge, or kvm-kmod from git?

Do not meddle in the internals of kernels, for they are subtle and quick to 
panic.
