I don't think this is possible. I'm not sure at all the CD has a way to
report whenever the eject button has been pressed or not.
There is a command which prevents ejecting the CD (the LOCK command);
the cd driver uses it.
You may be able to do what you want in hardware though; if you can disconnect
the eject switch from the CD circuitery and connect it in place of the ATX
Or maybe just remove the eject button ?
