I don't exactly know why it tries to load if_tap when it is already present, 
but FreeBSD should not allow it to be double-linked into the kernel. I 
created a patch that (hopefully ;) disallows this. You can find it at :
	http://hobbes.bsd-dk.dk/~npp/kern_linker.patch 

I would appreciate if you have the time to test this to see if it aborts the 
loading correctly. I know it's not exactly the real fix but it should stop 
some panics. 
Could you also test if unloading the if_tap module panic's the system ? This 
should ofcourse be tested without my patch and preferably when a tap device 
is in use.
