Comment 58 for bug 1038055

Testing today (on a Xen guest) showed that the X crash on unity startup seems to be resolved. On the KVM side at least startup works, while I get occasional crashed that look similar to the initial crash (maybe that is a result of a slower machine trying to cope with llvm-pipe). But in the light of that I would also tend to disable the kernel cirrus drm driver (even more as this currently would only do anything for KVM). That way we at least face the same stacks when running Xen and KVM guests.
