Disabling hal cdrom polling breaks functionality

Binary package hint: libnautilus-burn-dev

Reading http://www.lesswatts.org/tips/disks.php it is really worth it to disable hal cdrom polling as it prevents the power saving (important for laptops) from working properly.

However when you do this hal-disable-polling --device /dev/scd0 it leads into the cd/dvd image burning application to fail. It will keep asking for the user to insert a disc for writing even when one is already inserted.

I think that when I unplug my laptop from AC power the polling should be automatically disabled. Furthermore the cd burning application should be more intelligent (enable the polling if it was disabled and the user wants to burn a disc, and disable it again afterwards perhaps). This would require small touches to several packages (libnaulitus-burn?, hal?), and preferably upstream.
