Thanks.

Yes, please do it too!

We'll see. Personally I think yes, but of course it would be harder to
implement... We could start with a C only version first though, then maybe
add an asm one later.

Errata corrige: BeOS uses 1 buffer, then it converts from it directly onto
the video RAM.

Ok, this is good for me. But then we'd need a separated C file with this
function and all the C conversion functions in it; should we put this into
src/ or src/misc ? I vote for the first one.
Also, you should move update.s to src/i386 after the modifications...
