It might have worked in a.out if you actually loaded the kernel with all
the debug symbols... but there is no support for debugging symbols for
ELF objects, even though we currently use DBX-format deubgging in our
ELF.  It will become even harder when we switch to use DWARF2 debugging
info in our ELF (which will happen sometime this year).

If you really want source-level debugging, I suggest using kgdb.
