The problem is that a normal user has not the right to insert a module into the
kernel, even if he can execute modprobe.
What I would do if I was in your place is giving modprobe the suid bit by
typing : chmod +s /sbin/modprobe.
That means that when your run modprobe, it will execute with the owner's
permitions (here : root)
