Hello Marius!

Yes and No :)

Lets make it as list with short items:
1. Making these drivers work as low-level console.
2. Drivers priority.
3. Using hardware acceleration.
4. Using the 12 x 22 gallant font.
5. Allowing Xorg to map the frame buffer.
6. (Part of 5) Other register banks as needed.
7. Allowing late attachment.

Answers:
1. Works, I did testing on ARM board Efika MX with vt_fb_early driver.
(Still have to discuss several things with arm@ guys, then commit)

2. Works. F.e. amd64 start with vt_vga driver, then vt_kms driver
override it as more specific.

3. Not used at all yet.

4. I like that font. If you want more "gallant" - I will help. Thanks
to Ed, newcons support any font dimensions. 

5. It works, but only for those drivers which attach dev/fb/fbd, via
fbd devfs node (not accessible via vt(9) ioctls yet).

6. IMO better to put it into some drm emulation.

7. Works in many combination. (
start w/ vga, load kms; (kms replace vga)
start w/o driver, load kms;
preload kms, start w/ vga; (kms replace vga)
preload kms, start w/o driver; (kms attached after drm node initialized)
)

Have to put your list on Newcons's wiki page too.

As I remember such long list of requirement you provide was based on
expectation that I want to replace syscons right now :)
But, for now we (me and x11 team) want to see it 10.0 as disabled by
default (just like in HEAD now), so peoples who want to help with debug
of new xorg and drm drivers will be able to see messages after KMS-xorg
starts.

Oh, looks like I forget what I have to say more. :)
So it will be said later, when I will less sleepy. 

Anyway. Thanks a lot for your comments!!!
