Correctly parse the video information from the tagged list, so that we end up with the right bytes-per-char values. When booting with a tagged list rather than a param block, this allows the decompressor to display its messages during boot on the screen. (Boot loaders normally pass a param block on this platform, but the latest boot loader version recently released does not.)
