So let's solve this. So, as i understand the current prefered fix is : 

  1) if there is no /proc/device-tree/aliases/via-pmu -> we issue a warning.

  2) if the /dev/pmu device is not existent and/or not writteable
     -> we issue a warning, and don't use the feature

  3) if the /dev/pmu is existent and writteable -> we use the feature

By default, the /dev/pmu is not writteable, so the feature is disabled, so we
need to add a line in Debian.Readme explaining this, and also the relative
unsecurity of this approach.

Does this solve the issue ? Does this make the feature usable to everyone
satisfaction ? I would say yes, so let's do it and not speak about this until
the gnome 2.10 or whatever release which use the advanced hal thingy.
