[fedora-virt] Hey, my Win XP machine now bluescreens

I've had a Windows XP KVM running through several fedora upgrades and updates, and I just tried starting it for the first time since getting the libvirt-0.8.2-1.fc13.x86_64 update, and now it bluescreens. I had been running the redhat virtio disk and network drivers inside the KVM, have they gone incompatible on me? (I guess I could try switching the KVM back to IDE emulation and see if it starts working).
