Ah, got it.

The little aluminium door can be physically slid down to expose the cdrom
drive and then a paper clip can be inserted in the hole to force the
door open.

Now to make this machine boot properly again.

Or you could boot into Open Firmware (Cmd-Opt-O-F) and type 'eject
cd'. And then boot with 'boot cd:,\\:tbxi'.

I'm not sure if holding the mouse button down during upstart works  
without OS X, but that is the simplest I think.

The hold-mouse-to-eject-all feature is a firmware feature that's been
part of the Mac since way-back. It used to be the defacto way to eject
a floppy disk that wouldn't eject at the desktop :)

I am pretty sure it works on all PowerPC machines, regardless of the OS.

graphics card for PowerPC G5 and debian-6.0.3-ppc

I have debian-6.0.3-ppc installed on a PowerMac G5.

The graphics card used is a ATI Radeon 9600 AP (AGP)
with one backward key(1.5V key).

The board has one AGP slot; and 3 PCI slots (length ~125 mm).

1. Is it possible to use a Radeon HD 5450 PCI card with 
   debian-6.0.3-ppc?

2. Is it possible to use a GeForce 6800GT AGP card with
   debian-6.0.3-ppc? This card has one backward key(1.5V key)
   like the ATI Radeon 9600.

3. Must I buy a completely other card?

My understanding is that you need a card with Mac compatible firmware
on it.  A PC card will not work.  There are people that have managed to
modify the firmware on PC cards to make them work in Macs, but I have
no idea where to get info on doing that.

For Radeons, that's only true for older cards without ATOM BIOS,
basically anything older than Radeon X1xxx. So this shouldn't be a
problem for a Radeon HD 5450, but there might be other issues, e.g. the
drivers in the stable release might be too old to properly support that
card.
