Indeed, this is a serious bug. On my iBook G4, the module
therm_adt746x must be loaded, which controls the CPU fan. Without this
module, the fan is never enabled, even if the CPU gets very hot.

I will file a bug about this.

Try keeping it pressed for four or five seconds. This delay is
configurable in /etc/pbbuttons/pbbuttonsd.conf (EjectCDKeyDelay).
Debian sid has a nice gui for this stuff (powerprefs); unfortunately
it is not included in Warty, but you can install it from universe.

You can also set this up in powerprefs, or in the config file.

Don't know, my iBook does not have such fancy things.

Did you already try to adapt the mixer settings for the CD-ROM?
