- * * make vga_console_init take FB location, columns, lines and starting
- * column/line.
- * * track a word offset, and not columns/lines. The offset is needed more
- * often than columns/lines and the latter two can be calculated easily.
- * * then implement real vga scrolling, instead of memcpying stuff around.
