[Bridge] Source IP Modified on Broadcast Packet Through Bridge

I am encountering a problem where the source address on broadcast packets
seems to be altered to the local IP by the bridge netfilter. The details on
the issue are documented here
http://forums.gentoo.org/viewtopic-t-420158-highlight-.html. As a
workaround to this issue, I have disabled the bridge netfilter through the
proc filesystem with:
echo "0" > /proc/sys/net/bridge/bridge-nf-call-iptables
This workaround stops the source address of the broadcast packets from being
altered. However, it also precludes a firewall on the bridge adapter.
Based on http://lists.osdl.org/pipermail/bridge/2005-January/000804.html, it
seems that another workaround is to remove the iptable_nat module.
Has this been identified as a bug?
