Right :-)

I don't think that's the case for us.  HAL does the suspend on behalf of KDE by
calling pm-suspend.  HAL asks PolicyKit whether the calling user is allowed to
suspend, which is in turn determined by its policy files.  The policy should say
that the "active" user (as determined by ConsoleKit) is allowed to suspend.  It
did in the polkit configuration, but we probably lack the corresponding
PolicyKit configuration.

(To be clear: suspend worked in KDE until a few days ago.)
