Jesse's initial patch commit said:

"At panic time (i.e. when oops_in_progress is set) we should try a bit
harder to update the screen and make sure output gets to the VT, since
some drivers are capable of flipping back to it.

So make sure we try to unblank and update the display if called from a
panic context."

I've enhanced this to add a flag to the vc that console layer can set
to indicate they want this behaviour to occur. This also adds support
to fbcon for that flag and adds an fb flag for drivers to indicate
they want to use the support. It enables this for KMS drivers.
