Missing unwind data for module

Hi, Jeff -

I suspect what's missing is that when -d is used to identify kernel
modules, names should exclude the .ko, and the modules should be found
somewhere under -r or /lib/modules/`uname -r`/.  With the -d being
given a file name, it'll treat it as a user-space executable/shlib,
which won't work.  (We should make that work though as a heuristic.)
