The LGPL doesn't require us to publish the source code of individual .exe.so or .dll.so binaries if we're not basing them on LGPL code. I haven't checked the whole list, but most of these are programs CodeWeavers developed internally and thus controls the copyright on, and they mostly exist for integration with other components of CrossOver.
That doesn't mean we can't or shouldn't publish the code, just that we probably haven't considered it. At the very least, I think we want to publish the source code of anything that exists for Windows compatibility.
Note that ntoskrnl.exe is actually in the dlls/ directory of the Wine source tree, and it should be there in the CrossOver/Wine source code as well.
