* enables linear framebuffer and VBE 3.0 extensions. * add a number of new resolutions, up to 2560x1600, and including * widescreen modes common to modern displays. * Introduce configurable video ram size through the "videoram" config * file option, shrinking default video ram used to 4 Megs (thus * eliminating 4 wasted megs/VM that have been the case until now), but * allowing users to specify up to 16 Megs of vram, to support the * extreme high resolutions such as 2560x1600x32.
