Comment 5 for bug 1001825

Just something which may be usefull:

After ubuntu taking control of keyboard and mouse, and the keyboard not being setup correctly at mac startup anymore(no preboot hotkeys); detecting the keyboard at OS X login(just touching the keyboard power button or shuting down and restarting the keyboard) do not make the keyboard work at mac preboot; getting the keyboard to work at OS X itself after login does not work too; the only way to get the apple keyboard working at startup is to do the process shown at the mac manual(going to system preferences>keyboard>bluetooth configurations and detect the keyboard there)
