Yes. I think that may be generally true. I also wrote a "how-to" at the 
linhes wiki which may be a good starting point for others.
Link to the how-to: 
http://www.linhes.org/bugs/projects/linhes/wiki/Predictable_video_assignment_for_HD-PVR_using_udev

Some of the udev mount points and and links to it may be different in 
other distros so someone using this how-to should take that into account 
and verify your current mounts and links. For example, on Linhes (which 
is arch based), the hd-pvr mounts in /dev/v4l/videoX (where is a digit) 
and links /dev/videoX to it.

I only just wrote this prompted by own reply above yours and figured if 
I made a statement like that I should document it. :)
