One way to avoid this problem is to put the new rule(s) in a separate
rules file (I use 10-dvb.rules) that will be processed before the udev
default rules (the default udev rules are named 50-udev.rules) The
default rules can be overwritten if udev is updated, hence the use of
a separate rules file.) Also note that rules files are parsed in
lexical order, so to have a rule processed first, its filename needs
to come 'before' the default rule file.

For any users wanting to look into using udev for controlling device
creation, the following site is one I strongly recommend:

http://www.reactivated.net/writing_udev_rules.html

I used to use the rc.local method, but looked into using udev because
it seemed more powerful and 'cleaner'.
