Ah, my fault. That's because your 'origin' is now kiszka.org. Go to
kvm-kmod/.git/config and update the submodule url to
git://git.kernel.org/pub/scm/virt/kvm/kvm.git. Then do a 'git submodule
update' and proceed with the other steps.

I think (hope) that this is due to issues which are fixed in latest
kvm-kmod. Let us try to get the git version running first as it shall be
released as kvm-kmod-2.6.31 soon.
