My best bet from looking at it quickly, is that you still have 'gateway'
set in /etc/conf.d/net.  If you look at /sbin/runscript.sh, you will
see:

----------------------------------------------------------------
# Source configuration files.
# (1) Source /etc/conf.d/basic to get common configuration.
# (2) Source /etc/conf.d/${myservice} to get initscript-specific
#     configuration (if it exists).
# (3) Source /etc/conf.d/net if it is a net.* service
# (4) Source /etc/rc.conf to pick up potentially overriding
#     configuration, if the system administrator chose to put it
#     there (if it exists).

[ -e /etc/conf.d/basic ]                  && source /etc/conf.d/basic

[ -e "/etc/conf.d/${myservice}" ]         && source
"/etc/conf.d/${myservice}"

[ -e /etc/conf.d/net ]                    && \
[ "${myservice%%.*}" = "net" ]            && \
[ "${myservice##*.}" != "${myservice}" ]  && source /etc/conf.d/net

[ -e /etc/rc.conf ]                       && source /etc/rc.conf
-----------------------------------------------------------------

Thus, it sources your /etc/conf.d/net.br0, and then sources
/etc/conf.d/net, which resets 'gateway' again, and makes the
'[ "${gateway%/*}" = "${IFACE}" ]' bit always fail.

As I see it, you have two simple choices (other than hacking
things to pieces):

1)  Use something other than 'gateway' for the br0 script.

2)  Do not set gateway in /etc/conf.d/net
