Hmm, interesting.  I would guess that this means that you shouldn't run 
floating point code in the kernel.

Think about it for a moment; to whom would you deliver a floating-point 
exception?

It probably fails because the FPU initialisation is lazy, and if you 
haven't initialised it before you use it, you'll die screaming.
