What on earth are you talking about? Could you please re-read? I didn't
"treat badly" you, hwmon, acpi or whatever.

I'm simply pointing out the problem that 2.6.26 is going to break all
setups using lm_sensors 2.0 (which among many, many others includes
every single slackware and derivative system on the planet).

We are not having a flamewar. If you think that every disagreement or
pointing out of a problem constitutes as much, that in itself is a
problem but it's not mine. I reported the problem and then posted a
patch that solves it one particular way.

Another way to solve it _could_ be to just make up a device link if
something generic is available so that sensors doesn't trip over it in
the first place but I don't know if that's a good option. You might.

I haven't a clue what you're talking about. Treatment? What treatment? I
just want to get the above mentioned problem fixed and didn't suggest
anything else. Let's get the problem fixed.

Rene.
