 * $Log: drv_NULL.c,v $
 * Revision 1.6  2004/06/26 12:04:59  reinelt
 *
 * uh-oh... the last CVS log message messed up things a lot...
 *
 * Revision 1.5  2004/06/26 09:27:21  reinelt
 *
 * added '-W' to CFLAGS
 * changed all C++ comments to C ones
 * cleaned up a lot of signed/unsigned mistakes
 *
 * Revision 1.4  2004/06/20 10:09:54  reinelt
 *
 * 'const'ified the whole source
 *
 * Revision 1.3  2004/06/06 06:51:59  reinelt
 *
 * do not display end splash screen if quiet=1
 *
 * Revision 1.2  2004/06/02 09:41:19  reinelt
 *
 * prepared support for startup splash screen
 *
 * Revision 1.1  2004/05/31 16:39:06  reinelt
 *
 * added NULL display driver (for debugging/profiling purposes)
 * added backlight/contrast initialisation for matrixOrbital
 * added Backlight initialisation for Cwlinux
