Oh, i was not aware that they had still the crt2 code in there.
I removed the crt2 code from mga_vid when i ported it to linux 2.6
as it was never really working according to Arpi who developed it.
I must admit that i haven't had a look at the vidix code for
a very long time.

Uh.. i neither had the time to look at dfbmga. Yes, shame on me.

No idea. As i said, i do not own a TV, thus i never really
cared about TV-out.

Believe me, the mga code didnt change in the last 3 years much.
It didnt even change at all in the last 2 years, so you can safely
assume that the howto is still valid.

The more i deal with mga_vid and its problems, i get to the
conclusion that a truly openly documented graphics card is
a must have for the OSS community as otherwise we will run
out of graphics output devices is in the near future.
I hope, that the open graphics project will be a success.
