I confirm your analysis. However, I think this isn't a new issue. Before the 
aforementioned patch, running

# fbset -xres 640 -yres 480 -laced 0
# fbset -depth 16 -rgba 5,6,5,0

didn't produce any error, but didn't either resize the display to 640x480 or 
changed the pixel format. With the patch applied, the commands are rejected as 
they should be, as they wouldn't produce the expected results. The new 
behaviour is thus in my opinion correct.
