kvm_intel not loading with nested=1 on boot

On 12.10, when I boot my host, guests are not able to load the kvm_intel module because the kvm_intel module on the host is loaded without nested=1 (ie, nested virtualization is broken). I presume this is happening because the module is loading before the qemu-kvm upstart job runs. The upstart job works correctly in that if after a fresh reboot I do:
$ sudo stop qemu-kvm
$ sudo start qemu-kvm

I am then able to load kvm_intel in guests (ie, KVM_NESTED=" nested=1" was honored in /etc/default/qemu-kvm).

WORKAROUND:
Add the following to /etc/modprobe.d/qemu-kvm.conf:
options kvm_intel nested=1

I should note that because of bug #1040033, I am running 12.04's qemu. I verified that /etc/default/qemu-kvm between 12.04 and 12.10 are identical and that the upstart jobs should be equivalent (the 12.10 one adds '|| true' to the end of all modprobe lines).
