I found qemu to be tremendously accurate and thus time-saving. This patch adds the add-on/VGA ROM options and increases the image size. A real VGA is not yet working, no mode is set after power-on but qemu shows exactly the same behaviour. Requires qemu patches like on http://www.openbios.org/Open_Firmware
