Is this a feature or a bug?: system hanging if loading the if_tun module at the boot time while it is already compiled in the kernel.

The Issue:
Hi... we had the following issue:
    the system hanging with FreeBSD 7.1, amd64.

It seems that the reason in
loading the if_tun module at the boot time (/boot/loader.conf: 
if_tun_load=YES),
while it is already compiled in the kernel.

It appeared only when the OpenVPN appliance started and tried to use  
tun interfaces.

The Question:
Is the system hanging is to be considered "normal" in this case?
(in other words, is this a feature or a bug? =)) )

P.S.
the only related log messages we got in /var/log/messages were
<...>
/var/log/messages.1:Mar 10 11:32:10 gw-office-hpp kernel: Module if_tun 
failed to register: 17
