From the Linus threads I've read, even older IOCTLs will be shot down. The unmaintainability and randomness of IOCTL numbering schemes is one of the things that brought this about. Die, IOCTLs, die! Also, the DRM is destined to be merged with the fb layer, or at least more closely integrated. It's hoped that this'll allow us to depend less and less on X for graphics acceleration (i.e. only use fbdev for output). See lkml around May 14th, 2001, and the archives of linuxconsole-dev for more info. M. R.
