Sure.  Sorry for the delay, but I had to put my hands physically on that 
laptop in order to be able to make the check
Here is the result

For comparison purposes, I can also give you the same output on a DELL 
laptop where the novatel card does actually work

What is definitively different is the available IRQs.
