I can confirm this problem with the Flt 6 installer. I selected a Japanese 106-key keyboard, but the installer appears to default back to 101-intl. Further, once I complete the Ubuntu installation, I still can't get my 106-key JP keyboard recognized properly. From what I remember, this keyboard did work well in Breezy (after changing keyboard layouts in GNOME).
