Yes, it does not care about it. It just calls putchar() with a text position
and our driver has to render the character, just in the same way as it
did in the ite driver before. At least I hope so...

Are you sure? It looks like it switches into a special 4 plane text
mode, where the first plane contains the characters and the second
the attributes. That's exactly the same technique as in the vga console

You're absolutely right. I didn't know that it can switch to mapped mode
with SMODE. That's great!
