I think it's possible to use an alias in the /etc/modules.conf file, but as for exactly how to do that, I'm not sure.
It's something along the lines of:
alias /dev/ttyS04 /dev/ttyS03
or if the module for your modem is something like lt_modem, you might try:
alias lt_modem /dev/ttyS03
but this is only a guess from reading the modules.conf man page, I may well be wrong.
