+* This file is based on two CyberVision64 frame buffer device drivers
+*
+* The second CyberVision64 frame buffer device (cvision.c cvision_core.c):
+*
+* Copyright (c) 1997 Antonio Santos
+*
+* Released as a patch to 2.1.35, but never included in the source tree.
+* This is based on work from the NetBSD CyberVision64 frame buffer driver
+* and support files (grf_cv.c, grf_cvreg.h, ite_cv.c):
+* Permission to use the source of this driver was obtained from the
+* author Michael Teske by Alan Bair.

+* - 05 Jan 96: Geert: integration into the current source tree
+* - 01 Aug 98: Alan: Merge in code from cvision.c and cvision_core.c
+* $Log: cyberfb.c,v $
+* Revision 1.6 1998/09/11 04:54:58 abair
+* Update for 2.1.120 change in include file location.
+* Clean up for public release.
+*
+* Revision 1.5 1998/09/03 04:27:13 abair
+* Move cv64_load_video_mode to cyber_set_video so a new video mode is install
+* with each change of the 'var' data.
+*
+* Revision 1.4 1998/09/01 00:31:17 abair
+* Put in a set of default 8,16,24 bpp modes and map cyber8,16 to them.
+* Update operations with 'par' to handle a more complete set of parameter
+* values for encode/decode process.
+*
+* Revision 1.3 1998/08/31 21:31:33 abair
+* Swap 800x490 for 640x480 video mode and more cleanup.
+* Abandon idea to resurrect "custom" mode setting via kernel opts,
+* instead work on making use of fbset program to do this.
+*
+* Revision 1.2 1998/08/31 06:17:08 abair
+* Make updates for changes in cyberfb.c released in 2.1.119
+* and do some cleanup of the code.
+*
+* Revision 1.1 1998/08/29 18:38:31 abair
+* Initial revision
+*
+* Revision 1.3 1998/08/17 06:21:53 abair
+* Remove more redundant code after merging in cvision_core.c
+* Set blanking by colormap to pale red to detect this vs trying to
+* use video blanking. More formating to Linux code style.
+*
+* Revision 1.2 1998/08/15 17:51:37 abair
+* Added cvision_core.c code from 2.1.35 patches.
+* Changed to compile correctly and switch to using initialization
+* code. Added debugging and dropping of duplicate code.
