Hi all,
Here's the other panic I promised:
-cut-
zem# uname -a
FreeBSD zem.santala.org 4.5-RELEASE-p2 FreeBSD 4.5-RELEASE-p2 #5: Sun

zem#
(wait or generate traffic)
fatal kernel trap:
trap entry = 0x2 (memory management fault)
a0 = 0x0
a1 = 0x1
a2 = 0xffffffffffffffff
pc = 0x0
ra = 0xfffffc00004ff4c0
curproc = 0
dbbprinttrap from 0x0
ddbprinttrap(0x0, 0x1, 0xffffffffffffffff, 0x2)
panic: trap

-cut-
All you have to do is compile a kernel with bridge and firewall, enable
them with sysctl and wait or generate traffic.
Here's the sysctl.conf:
-cut-
net.link.ether.bridge=1
net.link.ether.bridge_ipfw=1
net.link.ether.bridge_cfg=rl0:0,de0:0
-cut-
The catch is that if you give one of the interfaces an IP address the
kernel no longer panics. Any questions?-)
