Hmm... I'd need to get access to that laptop to double-check, it is a
co-worker's, I just asked him to boot to Linux and noticed the poller
wasn't running.  I assumed that was hald doing its job properly, as he
said he never ran hal-disable-polling, and checked no further.

If I manage to get access to that laptop again, I will do a more
throughout check.
