I've been working on a different scheme for FreeBSD that supports kernel
threads and kernel modules and also works on non-i386 and non-amd64
systems without any gdb changes (at least, that's the intend -- I'm not
far enough in the development to have a working prototype of all features).
Anyway, it uses the remote protocol to establish an IPC pipe between gdb
and some front-end that knows about the quirks of the kernel and its core
files and isn't an inherently native solution.

I cannot prevent you from committing this, but if it doesn't address
the items mentioned above, it may not be used on FreeBSD.  Unless I'm
being relieved of gdb duties of course :-)

FYI,
