  Modified files:
    sys/i386/isa         sio.c 
  Log:
  Force success of the probe (after doing it as before except in one
  miscconfigured case) if the port is the console.  This fixes several
  bugs:
  - if all sioprobe()s failed, then the console driver followed null
    pointers in cdevsw[].
  - if the sioprobe() for the console failed but another sioprobe()
    succeeded, then init hung early when the console couldn't be
    opened.
  - it was silly for the console to not be there after printing boot
    messages on it.
  Bugs introduced by this are hopefully no worse than old ones caused
  by forcing the success of the `cn' level probe.
