Description of Problem:
The GNOME modem lights applet should add /sbin/ to the path of ifup
This is because regular users don't have /sbin/ in the path, and the modem
lights applet will silently fail to connect.
ugh, I already fixed this but the change got lost. Will redo.
may as well keep it all in one place...
