Enable Hotkeys on Lenovo SL Laptops in Linux

I've been looking for this kind of information since a long time, just as a friend of mine came up with this.
$ sudo modprobe lenovo-sl-laptop

And viola! The keys work.

To make this happen on every start-up, do this, add the following line to /etc/rc.local just before the last line of the file:

modprobe lenovo-sl-laptop

The keys should now work on every start up without a problem.
