BTW, has anyone contemplated or even done this - some sort of a script

Hmm, isn't this the task for asf(8). If not, what is asf(8) for?

This is a very nice command, thank you! But it does not seem to be
directly applicable to postmortem situation i.e. crash dump
debugging. Or maybe it will be easier to teach kldstat to work with
dumps/images in addition to what it does now ?

There is some support in /usr/src/tools/debugscripts/ but I didn't try
it recently. To make it work you need to to do smth like that:

cd /usr/obj/usr/src/sys/GENERIC/ && make gdbinit

From what I could tell, these were for remote debugging. I've written
a shellscript that wraps calling gdb -k (since we're using 4.x at the
shop). I'm not quite sure how to translate it into kgdb-feasible stuff
since kgdb doesn't have -x or -batch. If anybody would like to give me
pointers, I'd be glad to wrap it for either.

It's available at http://databits.net/~dho/load_syms.txt

You do know about:
http://www.freebsd.org/cgi/cvsweb.cgi/src/tools/debugscripts/

If you want to write up an entry for the README, I'll add it to the
collection..
