This is still harmless, though I hope that I have caught most of the
cases where it occurs.  Userland (mesa) may still call this ioctl with
the wrong or both crtc's though.  It is converted back to a debug
message in HEAD.

This is all fixed in HEAD.  It is waiting jhb@ to MFC r194644 to get
-STABLE fixed up.  I have additional MFC's to cleanup vblank support
issues, but the primary issue is that msi interrupts don't work after a
vt switch without the above MFC.
