But even 16 bit words doesn't seem possible ; a color register has only 
12 bits in STE mode (bits 12-15 are set to 0).

Maybe in falcon these bits can store informations, but that would be 
surprising as this can really break compatibility with many programs 
that try to run in STF/STE mode on Falcon.
