It's been tested on U8100 only but it only changes/adds the files listed below so it should work on any QVGA device:
/system/media/bootanimation.zip (scaled and cropped to fit QVGA)
/system/media/audio/ringtones/R2-D2.ogg (it's actually meant to go with the bootanimation but it works well as a ringtone)
/data/app/(4 different live wallpapers).apk
Have fun... And don't thank me, thank Motorola and whoever leaked it.
