Is this correct? Shouldn't it be this:

rcFCB->RFCB.IsFastIoPossible = !FastIoIsNotPossible;

There exist three values FastIoIsPossible, FastIoIsNotPossible and 
FastIoIsQuestionable. I was simply trying to disable the fast-io 
support, because it is not implemented. It seems that W2K doesn't use 
this value. With zero pointers W2K does always crash. This was the 
reason for implementing the fast-io stubs.
