Yes. Just tried again. Clarification: triggers on a "halt -p", _not_ on
a reboot.

It triggers it immediately (in my laptop), I tried from a text console
and it spews things and at the bottom a poke_text thing like before
(after a while I got a couple of messages from iwl3945 about a timeout
and somehow it started to reboot, either when I pressed the power button
or when I did <ctrl><alt> )

Three lists attached, first all modules after I login, then modules
after a single user boot and then two more after I removed bluetooth and
80211* modules on a hunch, fails to power off in all cases (I first saw
a ref to blue something at the very top of the dump, so removed that,
then saw a reference to 80211 at the top, removed that, then I gave
up :-)
