Well, HAL spits out lots of events, sure only some are useful. That's
because HAL doesn't try to enforce any policy; it leaves that to e.g.
g-p-m.

One question: how can you trust the events that g-p-m would send to
upstart are genuine? Ie. how do you ensure that they don't come from a
malicous attacker? Seems like you can't do this securely...

Right. That's, for example, why I filed 

 http://bugzilla.gnome.org/show_bug.cgi?id=333031

for g-p-m to run user scripts when significant events happen.
