    drm/radeon/kms: don't enable connectors that are off in the hotplug handler

Can I have you do one more test as well... could you try the latest upstream v3.1-rc8 kernel? I'd just like to also verify this hasn't already been resolved with another patch. I've posted a v3.1-rc8 kernel at the following location:
