Comment 61 for bug 337935

Stupid me: it's the Gnome settings which disabled taps and stuff like that. I just found out that with my fdi file in place, taps worked all right in the gdm login screen, but failed once the session was started. I found the corresponding settings in System / Settings / Mouse / Touchpad.

So I take back my complaints: things work, only the Mactel guides talking about fdi files need adjusting, as settings are now per-user and not per-system. If you can manage to log in without those settings, that is.
