It looks like given the helpers that you've added, converting the PCI devices is more or less programmatic. IOW, it just requires an appropriate sed. I'd rather see an all-at-once conversion of the PCI devices than just convert over a couple functions. In fact, we can go a step further after that and start poisoning symbols to prevent the wrong interfaces from being used.
