Multiple IP addresses in a Jail

Perhaps there is another way to do this, but I am trying to layout as 
fault tolerant a network architecture as possible.  Most rack mounted 
boxes come with at least 2 Ethernet ports for what one would assume is 
to have each go to a separate switch (or to act as a firewall).  If 
either switch goes Tango Uniform, the network is still up.  But if my 
processes are running in Jails and I create an IP alias for each network 
interface for the jail, I need to specify 2 IP addresses for the Jail, 
not one.  I had heard there was a patch to do this and that it had been 
added to FreeBSD 5.3.  Is this not the case?  Is there a patch?  Is 
there another way to do this?  Thank you.
