I *think* the suggestion was to add sysfs nodes for ACPI objects so that
the assosicated kobject could be the "source" argument to the uevent API.
Not that each kobject would have an event stream of it's own :)

I'm not deeply into ACPI, so I'm not sure if it is possible to enumerate
all event sources, or if GPEs would come from nowhere...
