(Get the code!)
For the record, the hal-addon-storage had a poll loop which regularly queried the CD-ROM whether the eject button was pressed, and if so, emit an "EjectPressed" device condition through d-bus. Something in the desktop session (usually nautilus) would pick that up and ask hal to eject the drive.
This mechanism is completely lacking in DK-disks, so it's not a small change. Also, I'm not sure whether we actually want this kind of callback back in DK-disks.
One possible alternative would be to not lock the CD-ROM tray when mounting. This leads to much less clean unmounts, since the device would disappear while it is still mounted (and then the kernel/userspace have to clean up afterwards). For read-only media like CD-ROM or DVDs this does not actually pose a problem, though.
