Controlling the fancy LEDs on DELL XPS Gen2

[Stefan Kanarski]

Hello again,

if anyone from Dell could tell me where I could find documentation or where 
else to ask for this, please don't hesitate to tell me. I would be pleased 
like a little child if I could control the LEDs from my Linux. :-)

With best regards

Stefan
