Well, this is a very old thread and the user that originally posted it doesn't frequent JustLinux anymore. I don't use ADSL myself, but glancing through the script it looks like you'll need to alter the restart function and possibly the "if [ ! -f /var/run/adsl.pid ]; then" line since those two things will probably be different now in Mandriva. Basically figure out how you would normally restart your connection and then stick those commands in the restart function, and maybe even remove the check for whether it's running entirely, since I suspect it's not necessary.
