    VBE: Skip graphics mode setting for non-VGA devices
    
    This hit me when running the latest Qemu with coreboot:
    First the graphics OPROM is running, then an iPXE OPROM.
    The iPXE OPROM has no int10 support (obviously) so calling
    vbe_set_graphics() wipes the framebuffer information from
    the coreboot table.
