I have the same problem, and the workaround Daniel Ellis described (booting with a DVD or CD in the drive) works for me also. If I don't boot with media in the drive my DVD/CD drive is basically dead in the water. Even though I can manually mount it, I can't burn anything to it because Brasero doesn't recognize it. The eject button also doesn't work. Curiously though, K3B does work for mounting, burning, and ejecting.
However if I boot with media in the drive everything works fine. The media is automounted, I can eject it with the button or via Nautilus, and continue to insert, use, and remove media normally.
I'm running Karmic Alpha 6 x86_64 and update every few hours, so as of this moment everything is up to date.
