display-svgalib : Display fullscreen using SVGAlib
display-svgalib: [-physz=<sizex>,<sizey>[dpi]]
Uses the SVGAlib library to display fullscreen on a VGA-compatible graphics card. You may need to be root in order to have IO permissions to drive the VGA device.
This option will provide a physical screen size for applications which wish to remain resolution independent. :p:`sizex`, :p:`sizey` are the x,y size of the screen in millimeters, unless the optional dpi string is affixed, in which case, they represent resolution in dots-per-inch.
