Patch 2, 4 and 5 looks good to me. Patch 6 causes artifacts on mode change, if the new mode is smaller than the previous.
Indeed. But I had no better idea (thats why it is tagged as "workaround"). Suggestions are welcome.
Would it be possible to include a 32bit memset into seavgabios ? That way there is no need to call a BIOS routine to clear the memory.
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.
