They're meaningless without your kernel, but even then all you're going 
to be able to tell is where in the fault handler things died; you won't 
know the address of the original fault.

There's nothing immediately obvious in the xl driver that would suggest 
that it uses excessive kernel stack either.  8(  Maybe someone has some 
clues on measuring stack usage (or simply on how to increase the kernel 
stack allocation...).
