That's one possibility.

No, that's gdb.

A lot depends on exactly what you want to do.  There's an man page
gdb(4) in -CURRENT which will, to some extent, help you with remote
debugging.  Note that the macros mentioned are in 4.8, but they're in
a different form in the directory /usr/src/sys/modules/vinum.  You'll
have to play around with them to get them to work.  Also, 4.8 does not
support debugging over firewire.
