That's okay - the patch is intended to start discussion anyway.

There is no added delay for the bootsplash.  However, it does take
time to decompress it.  On my machine it can take between 200-300ms
for the jpeg code.

It may make more sense for SeaBIOS to only bother with the bootsplash
if the boot menu is enabled (or some new option) - as otherwise the
picture is basically cleared immiediately after it's shown.
