Dell Latitude E6530, linux-next 20141208 plus the 3 patches you
posted on Nov 30 (support labels), plus the 4 of 3 patches in
this go around, and sensors reports:

i8k-virtual-0
Adapter: Virtual device
fan2:        2774 RPM

and under CPU load, that number rises to 3200 or so, so it seems to be
working....

So you probably should fold this into the current set of patches, and
feel free to put this in there:
