Cool.

If you need to read stuff off /dev/pmu you should just use helper_invoke
()
much like hald/linux2/classdev.c:hotplug_event_begin_classdev() does.
You
want to put the source in hald/linux2/probing and call the binary
something
like hald-probe-pmu. For packaging this can be setuid root and only
executable by the haldaemon user like we talked about.

That binary should use libhal to set/get properties. That's what we
currently
do for input devices, look at hald/linux2/probing/probe-input.c (and
I've
just fixed a bug here to cope with the new libhal API, so you want to
cvs up).

Does that makes sense or am I way off?

Cheers,
David
