        Fix display issue on terminals with screen size other than 80x25 
        (e.g. gfxterm with resolution higher than 640x480).

        * normal/main.c (grub_normal_init_page): Display title text in a  
        position relative to the center of the terminal instead of reliing
        on a hardcoded offset.
