Yes, having pondered the situation since my original message, it
occurs to me there may be a mismatch between Xorg compiled from a port
(I think it may have been rebuilt) and a driver installed via pkg. How
would I check?

Yes, I'm running HAL. I understand this is what makes detecting a USB
keyboard (I have a *full size* keyboard this way) and a USB mouse (my
precious trackball) possible.

service reports that hal is running. ps doesn't indicate anything
amiss (at least as far as I know):

hald is running as pid 1331.

So how would I get a prompt back in this situation?

Okay, so see above. When installing the system (it's a fairly fresh
installation), I really didn't have to do anything to make all this
work. One of the very first things I installed was gnome2 and I set
the relevant variables for HAL, dbus, and gnome.

But I wouldn't be the least bit surprised if an input component hasn't
been updated properly. Is there a sane way of making sure all this is
done right?

These seem to assume I have an xorg.conf. I was getting by without.
And Xorg -configure doesn't work. So now what?

thanks!
