You are mixing up the two bridge drivers. There is the old bridge(4)
which is the old you have compiled in and this uses the sysctl interfac
e to configure it.

Then there is the new bridge driver called if_bridge(4), named as such
since 'bridge' was taken. This is the one that uses cloned interfaces
which show up in ifconfig and seems to be what you are after.

In your kernel config just change "options BRIDGE" to "device if_bridge"
and it should all work fine. You can see the differences in each man
page.
