It appears to me (empirically, not from code inspection) that there may
(at least in some cases) be a delay between the time hald(8) starts and
the time that X can actually use it in a useful way to determine
information about the mouse and keyboard.

I ended up augmenting my xdm(1) start-up script's "start" stanza with:

...
# REQUIRE: ... hald ...
...
. /etc/rc.subr
...
        until hald=$(check_process hald-addon-mouse-sysmouse); [ -n "${hald}" ]; do
                info "$name start-up waiting for hald-addon-mouse-sysmouse"
                sleep 1
        done
        until [ -r /proc/${hald}/status ]; do
                info "$name start-up waiting to read /proc/${hald}/status"
                sleep 1
        done
        # This can actually be done as a single expression, but that helps
        # neither debugging nor comprehension.
        hald_start=`awk -F "[ ,]" '{print $8}' /proc/${hald}/status`
        now=`date "+%s"`
        # This was determined empirically
        hald_delay=8
        wait=$(($hald_start + $hald_delay - $now))
        if [ $wait -gt 0 ]; then
                info "$name start-up waiting $wait seconds for hald-addon-mouse-sysmouse"
                sleep $wait
        fi
...

With the above, I've only had the "non-responsive keyboard & mouse"
syndrome a couple of times (out of about 2 dozen or so xdm start-ups)
in the last several days.

Mind, I don't consider that a "solution" -- it's a hack.  But if
it helps....  :-}

Peace,
david
