I don't know if it would help but it might make sense to have a config option that can be used to mark drivers that are known to have problems, in these scenarios. CONFIG_BRITTLE_INIT perhaps? It would at least make it easier for people to see which drivers they don't want to use, and give people some incentive to fix things.
