NetBSD comes with it's own kernel debugger, ddb(4). If you do not port
to a new processor architecture, that will be available imediately.

Depends on the port, it needs machine dependend support. Once you have that
in place, it is the best option you have available.

Practically: no. It might work on some ports with certain hardware,
but in general it does not.

Usually ddb is the first thing you use for that. You can use gdb on another
machine to map the assembler code to C code.
