Good to hear!
Now, when this machine panics, I see:
<stack trace>
Waiting for remote debugger connection.
Options..... Type
------------ ----
continue.... 'c'
reboot...... 'r'
enter kdb... 'k'
However, I cannot seem to type anything on the "graphics" console.
I was logged into the console at the time of the crash in text mode,
via entering >console as the username; eg no windowing was running.
Do I need to be running with a serial console? Or doing anything else
differently? Or is it looking to talk kdb over the network?
Yep, it's over the network. I think it might be possible to do it over
serial but since I have 2 macs ethernet works for me (and I've not had
to debug ethernet recently;-)
Some debugging info is in the Developer Documentation, also found @ :

HelloDebugger.html

FWIW, the behaviour is the same (minus kdb) with the 1.4 kernel which
ships with OS-X 10.1
BTW, does devfs_remove() work? I don't see any other code using it,
and its where my current panic is happening (on the 5th call to it,
out of 64 device nodes).
