Okay that case does not occur. I have a couple of further API questions.

How about reading 3 bytes past the end of the bitmap.
I have noticed that 3dfx driver carefully avoids this,
but if this were allowed, it would avoid having a special case for
the last 3 bytes.

Why not make the fbcon colormap 32 bits in 16 bpp modes too.
This would use some extra bytes, but would avoid deciding
between reading 16 or 32 bits from the colormap in putc and putcs.
