Yes, upstream went away from using start/stop to only use "auto" some time ago. But a patch was kept in the Ubuntu version to retain the start/stop options, probably because of interactions with acpi-support. I am not sure if this patch is needed any longer. Testing would be welcome, as well as comments from for instance Matthew who I think was pretty involved in these changes.
