Most of the logic is in the gdb stub, which lives in the kernel. You
don't have to use -k to be able to remote debug the kernel. It may
have to be a cross-debugger (host=*-*-linux*, target=*-*-freebsd*).
In principle it should not be necessary, provided the host and target
architectures are the same.

In short: try it. chances are it works. If not, try with a cross-gdb.

HTH,
