Indeed.  But I had no better idea (thats why it is tagged as
"workaround").  Suggestions are welcome.

We are running real mode, so the framebuffer is out of reach[1].  As far
I know the bios routines switch to 32bit mode temporarely.  seavgabios
could try to do that directly instead.  But I have my doubts that it
will work better (havn't actually tried though).


[1] except for the setup code which runs in big real mode so 32bit
    access works there.
