Yeah, but that seems to defeat the purpose of dwarfless probing.
Maybe extend -d to accept a (presumed) kernel symbol table file

  -d /lib/modules/`uname -r`/build/System.map

And the kprobes.* logic can add this to session.unwindsyms.  For
that matter, it could read the file (like in jkenisto's older
symbol-table-based probing implementation) to verify placement
of kernel-side symbol probes.
