Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+ *  linux/drivers/video/fbcon.c -- Low level frame buffer based console driver
+ *
+ *	Copyright (C) 1995 Geert Uytterhoeven
+ *
+ *
+ *  This file is based on the original Amiga console driver (amicon.c):
+ *
+ *	Copyright (C) 1993 Hamish Macdonald
+ *			   Greg Harp
+ *	Copyright (C) 1994 David Carter [carter@compsci.bristol.ac.uk]
+ *
+ *	      with work by William Rucklidge (wjr@cs.cornell.edu)
+ *			   Geert Uytterhoeven
+ *			   Jes Sorensen (jds@kom.auc.dk)
+ *			   Martin Apel
+ *
+ *  and on the original Atari console driver (atacon.c):
+ *
+ *	Copyright (C) 1993 Bjoern Brauel
+ *			   Roman Hodek
+ *
+ *	      with work by Guenther Kelleter
+ *			   Martin Schaller
+ *			   Andreas Schwab
+ *
+ *  Hardware cursor support added by Emmanuel Marty (core@ggi-project.org)
+ *  Smart redraw scrolling, arbitrary font width support, 512char font support
+ *  and software scrollback added by 
+ *                         Jakub Jelinek (jj@ultra.linux.cz)
+ *
+ *  Random hacking by Martin Mares <mj@ucw.cz>
+ *
+ *	2001 - Documented with DocBook
+ *	- Brad Douglas <brad@neruo.com>
+ *
+ *  The low level operations for the various display memory organizations are
+ *  now in separate source files.
+ *
+ *  Currently the following organizations are supported:
+ *
+ *    o afb			Amiga bitplanes
+ *    o cfb{2,4,8,16,24,32}	Packed pixels
+ *    o ilbm			Amiga interleaved bitplanes
+ *    o iplan2p[248]		Atari interleaved bitplanes
+ *    o mfb			Monochrome
+ *    o vga			VGA characters/attributes
+ *
+ *  To do:
+ *
+ *    - Implement 16 plane mode (iplan2p16)
