dwarf info in modules.

That's odd.  Did you install your .ko into /lib/modules/`uname -r`/kernel?
That is where systemtap (libdwfl) looks for the .ko files.  It won't find a
module you built yourself unless it's in that directory.  (In future we can
add some options to look in other places for nonstandard modules' .ko files.)

Please post (or file in bugzilla) the failure mode using a standard module
like microcode, and a probe on a non-__init function.
