[ydl-gen] dvi/video out on alubook 1,67 ghz (powerbook 5,6)

[Benoit Chesneau]

Well, I would like to use linux+xorg on the laptop. I still can't
understand why xorg can't do dual head at least with the 20" cinema
display I have.I could have spanning screen without problem on macosx so
this shouldn't be a problem of vram.

I tried this method :
http://ozlabs.org/~jk/docs/mergefb/

But still no success. I have to investigate more.

Regards.

- Benoit
