I don't think so, at least in my case.  I had stuck some "ls -l" logging 
in my scripts.  When it gets to my script I get something like:
rw------- root root /dev/video1

After waiting a while, I get
rw-rw---- root video /dev/video1

If ivtv isn't loaded there is no /dev/video1.  It seems more like the 
module is loading but then the udev rules aren't being applied for a 
while.  I'm not sure what's causing the delay but it can be 6 seconds or 
more in my case.
