The screen driver works like a charm, but I found a slight problem
with the mouse driver.  I got:

  fs: filesystem panic: bad major device 7

It turns out that an entry needs to be made in the table of drivers in
fs/table.c.  The last few lines should read like this:

        tty_open,  rw_dev,      no_call,    TTY,         /* 4 = /dev/tty0 */
        no_call,   rw_dev2,     no_call,    TTY,         /* 5 = /dev/tty  */
        no_call,   rw_dev,      no_call,    PRINTER,     /* 6 = /dev/lp   */
->      no_call,   rw_dev,      no_call,    MOUSE        /* 7 = /dev/mouse */
    };

    int max_major = sizeof(dmap)/sizeof(struct dmap);


I'm not 100% sure this is correct, but it works for me :-)  Perhaps Eric
could confirm this ??  I guess he may have just overlooked this diff...

Recompiling with this fix makes the 'sketch' program work OK.
