IMHO that is the best solution to the problem because it will be using
code that has been heavily tested by the vendor. The one thing x86 Video
BIOS'es can do reliably is POST the graphics card ;-)
I'm just going to take your word on this since you have messed with far
more video bioses than I. I've just got a few too many scars over the
years from trying to make the whole BIOS sub-system robust enough for
embedded standards.
That would be nice if you could trim it down ;-) Would certainly save a

lot of code bloat. But if you do that, then you would need this code in
the kernel since now it would be the boot loader as well ;-)
Exactly. Which is why I like your project and I think its a good thing.
The only reason I have to carry around the legacy BIOS baggage is
for video.
How big is your in-kernel implementation?
