When we add the call to insmod in /etc/rc.local, we need to escape the backquote characters, so that they appear literally in /etc/rc.local. Otherwise, substitution happens when that file is created, resulting in a kernel version-specific path. Then the module won't load properly if booted into a different kernel.
