["Bridgman, John" <John.Bridgman@xxxxxxx>]

I have stopped estimating dates since we missed the last two estimates
as we learned more about the new 3D engine. 

What I can say is that we have the 6xx and 7xx chips drawing things in
house with our code (a demo program running over drm), that we have
pretty much all of the required functions working, and now need to :

(a) implement those functions in the 2d and 3d drivers, and 

(b) finish the IP review for just the information needed to make that
code work

I don't really want to even speculate re: dates but we're fairly close
now.

Hello John,

I fully agree with you. Is there any approximate ETA for the 6xx 2d/3d
acceleration?

Thanks.
