* constab is the console configuration for this type of machine.
* XXX - it should probably all be configured automatically.
* This entire table could be autoconfig()ed but that would mean that
* the kernel's idea of the console would be out of sync with that of
* the standalone boot. I think it best that they both use the same
* known algorithm unless we see a pressing need otherwise.
