The warnings are intended; the kernel will behave as before they were 
introduced.  I'm monitoring reports and looking at them as they come in. 
 They are harmless as long as the ioctls have always failed, and so far 
this has always been the case.  As soon as we are reasonably certain, 
the warnings will go away.
