    Console code will need serious work anyway; note that current names
    do _not_ refer to tty devices - there is some overlap, but right now
    we have
    * console drivers
    * some of them being connected with tty drivers; those can tell
    which tty driver corresponds to them
    * console ouput code maintaining chain of console drivers; output
    is sent to them, attempt to open() /dev/console ends up picking the first
    console driver that has corresponding tty one (== has console->device())
    and opening the tty device in question
    * unholy mess with redirects.

    There's no device nodes for console drivers. So names in console=... are
    something very odd, indeed.
