That means you have full control over what drivers are used, which makes
things even easier. You can just code for SDL and the try svgalib, fbdev
and raw X with DGA 2 and see what works best for you. You don't have to
support multiple pixel formats (ie 8, 15, 16, 24 and 32 bits/pixel)
either, as you can dictate the choice of hardware and driver settings.
