(David Dawes) + * + * 01/2003 - Version 0.2.0: Mode switching added, colormap support + * implemented, Y panning, and soft screen blanking implemented. + * No acceleration yet. (David Dawes) + * + * 01/2003 - Version 0.3.0: fbcon acceleration support added. Module + * option handling added. (David Dawes) + * + * 01/2003 - Version 0.4.0: fbcon HW cursor support added. (David Dawes) + * + * 01/2003 - Version 0.4.1: Add auto-generation of built-in modes. + * (David Dawes) + * + * 02/2003 - Version 0.4.2: Add check for active non-CRT devices, and + * mode validation checks.
