Change 76907 by marcel at marcel_nfs on 2005/05/13 03:04:49

	Add a seletal driver for the Intel 830M GMCH. The purpose of
	this driver is many-fold:
	o  Help to create the right logical infrastructure,
	o  Experimentation with 2D accelerated hardware for BitBlt
	   operations,
	o  Experimentation with multi-head configurations to aid in
	   designing the right infrastructure for assigning keyboards
	   to displays (multiplexing and so on),
	o  Have an accelerated driver to preempt the VGA driver for:
	   +  purposes of having the VGA ISA bus front-end called at the
	      end of bus enumeration and making sure this doesn't create
	      a conflict,
	   +  implementing the logistics necessary for gmch(4) to take over
	      the console from vga(4),
	o  Gumption builder or project show-stopper.
	
	This code only causes gmch(4) to attach. Nothing else is
	being done yet.
