bugref:8087: Additions/x11: support non-root X server: make sure that screens start out at a resolution of 800x600 in case the windowing system on top cannot handle hot-plug and resizing. Make sure that this does not get remembered as the next start-up resolution. Also remove support for mixing VESA and the kernel graphics driver: we no longer load the kernel driver if VESA is active.
