Backslash, German iMac Keyboard and OpenFirmware

I had problems typing the backslash “" and bar “|” on my iMac keyboard when in the OpenFirmware user interface.

The “" key on US iMac keyboards seems to produce keycode 57 (in X11). There is no key on the German keyboard that produces keycode 57. There is one with keycode 58, the “#” key.
