Loopback problem

I have two machines (that I know of) that have the same problem. The loopback interface has no ipv4 address, and it doesn't start up on boot. If I bring the interface up (ifconfig lo0 up),. it has no ipv4 address. If I bring it up this way - ifconfig lo0 inet 127.0.0.1, then I have an ipv4 address and everything works fine.

On box is 5.4 SECURITY. The other is 6.0 SECURITY. Both boxes have ifconfig="lo0 inet 127.0.0.1" in the /etc/defaults/rc.conf file. Both boxes boot fine and work fine, except for this one problem, which has manifested odd symptoms from time to time but never merited investigation (until now.)

Since I did the installs on both boxes, I've obviously missed something during the install (or chosen the wrong option). Does anyone have a clue what it might be? Or how I might fix this problem so the boxes will bring up lo0 at boot?
