I'm upgrading the preinstalled version of Ubuntu on the Dell Vostro V130 notebook. During the upgrade, there were some errors concerning the dell-laptop kernel module.
What is this module, and what does it do?

The driver in question can be found here:

On a quick scan of the code, it looks like it handles the rfkill switch (airplane mode), and backlight control.
