Is it just under Linux that you have this problem?  Personally I'd suspect 
that the keyboard/mouse/touchpad assemblies aren't seated properly, and 
perhaps that the corresponding cable isn't correctly seated on the planar.

Of course if this happens under one OS but not others, I doubt that's the 
case...
