KMS drivers really should all be able to restore their display state on resume without fbcon helping out. So make this the default.
Since I'm not entirely foolish, make it only a default, which drivers can still override. That way when the inevitable regression report happens I can fix things up with a one-liner plus FIXME comment that someone should fix up the suspend/resume code in that driver. But at least all new drivers won't be broken by accident because "suspend/resume worked when I tested it" as soon as you turn off fbcon.
