* loader/i386/linux.c: Include `<grub/video.h>' and
        `<grub/i386/pc/vbe.h>'..
        (grub_linux_setup_video): New function.  Loosely based on the EFI one.
        (grub_linux32_boot): Attempt to configure video settings with
        grub_linux_setup_video().
        (grub_rescue_cmd_linux): Set noreturn=0 in grub_loader_set, in order
        to avoid grub_console_fini() which would step out of graphical mode
        unconditionally.
