No, firewall_type=3D"open" will work even without the default-to-accept kernel config option. The presence or absence of the kernel configuration option determines what rule 65535 will be at startup: at the initialization of the ipfw framework, it places a rule numbered 65535, which is either 'allow' if the option is present, or 'deny' if it is not. The firewall_type=3D"open" rc.conf knob determines the behavior of the /etc/rc.firewall script (which can be overridden by setting firewall_script=3D"something else" in /etc/rc.conf) - and rc.firewall's 'open' mode creates a rule numbered 65000. Since ipfw terminates the rule search on the first match, rule 65000 will be processed before rule 65535, and the kernel's default will never be considered - firewall_type=3D"open" trumps the presence or absence of the IPFIREWALL_DEFAULT_TO_ACCEPT option.
