This clears up lots of things. If you don't build clean and

transition a driver from a NKE to an IOKit module, then the file that

is generated by project builder may not get regenerated. Though I'm

still puzzled because that means that the system doesn't know that

your module contains IOKit classes. Do you subclass any IOKit

classes or do you just use them straight?

I subclass IOService and IOUserClient. I didn't have any problems with it being loaded and called. Matching worked fine and my client app had no problem talking to it. Somehow, the unsupported mix was working. Dean's suggestion to call my NKE start/stop methods from init() and free() seems to work well. I am concerned about safety if the NKE fails to unload, but otherwise the process seems good.
