I prefer the option to specify the base baud rate in setserial from a
startup script. Having the additional ports at BAUD 0 (unusable) until
some explicit action is taken strikes me as a safer option, provided
this gets properly documented in the kernel Documentation directory and
in Linux HOWTO docs.
