Gods, I hope so. It would be about time.

Sure. As long as you have your BIOS setup to ignore "no video" errors.

That would be a good thing. Though I would think the detection might be a
bit difficult. I presume you are asking the kernel to drop into serial
mode if no video is detected ..... this should be relatively trivial as
the kernel init code already checks for the presense of said video....

# There are patches for both 2.0.27 and 2.1.17. These patches are
