- Treat VGA extension name other than "none", "vbe" or "cirrus" as a VGA compatible device plugin and try to load it. - Added new plugin type PLUGTYPE_VGA for such a plugins (interally handled like a core plugin). - Added panic in devices init for the case no VGA compatible plugin is present. - Added new method vga_redraw_area() that handles the non-VGA and null size case. The specific method redraw_area() is called otherwise. - Moved init_systemtimer() call from extension code to init_standard_vga(). - TODO: Implement VGA subsystem in the Voodoo code to test the new feature. Voodoo Banshee 2D accelerator code needs to be written to make this really useful.
