The thing to bare in mind about DGA (like SVGAlib) is that only programs
running as root can use it... (unless something has changed this in the
last couple years.) Try running your test program as root and see what
happens... Also SDL looks at the SDL_VIDEODRIVER environment variable
to help it pick which video driver to use...
Look at http://sdldoc.csn.ul.ie/sdlenvvars.php for more details.
