gnome-settings-daemon 2.32.0-0ubuntu3.1~test1 from your PPA works fine on my Dell Latitude E6400 (BIOS version A20, which is not the latest one available) with Maverick.
Fn+F8 cycles through the different output combinations and I didn't see any keypresses passed to active text fields (neither characters nor returns).
