Multiple routes to same destination?

I am using Zebra, but it will only keep one route to the same destination in the routing table at any given time, even if there is more than one valid path :( :(
I know that Linux has this built-in, and more searching of the 'Net after posting my initial question revealed that multipath routing is in fact something that many people have been asking for since FreeBSD 3.x.  I was hoping it would have been built into FreeBSD 6 by now.

this is not a scientific answer, but since no one 
else replied, here is what I found a while ago...

When I installed Freebsd 6, i did a lot of 
reseach/posting and found out that there is no 
way freebsd will handle multiple routes to the same destination
I was hoping to have two default routes for 
redundancy (and if possible, load balancing)

I never heard of a kernel patch, and if there was 
one, I wouldn't feel confident with it (just my opinion)

I then went with a routing package (there is 
zebra and quagga) which kinda did the trick. (I 
used quagga since I had some problem setting up zebra from the ports).

It works fine but adds a level of routing that 
could have been handled by the kernel I guess.
