You are right, or, well, I have had an S3 VGA card plugged in and been
scratching my head wondering how I should get the damned thing to
work.

Now I *know* there is not really a way for me to make this work
with the kernel only.

I'm on U-boot for this thing, I wonder if that can do x86
emulation to initialize VGA card. I guess I'm about to learn.
