The Ewoks concil said it's fine to dereference null pointers in the kernel, so, partly revert r70819 (by partly, I mean: revert everything excepted the comments that were fixed!).
Also add asserts that exist on Windows to make it obvious we're about to kill the whole kernel

To make it clear: fix the FSD!
