What I like about that is that it removes a lot of lines of code.
I hope you can get it small and simple enough that it becomes very
stable.
Tell us when you want some testing and we'll provide.

Any new ideas how to get cache coherency, or how to avoid the need for it?

Chris Wilson reintegrated the legacy UMS and put it in his "legacy" branch,
to make it easier for people who are on their own to work on it together.

I don't care about opengl, this thing can't do anything opengl for real anyway.
All I want is stable and fast 2D rendering. :-( Full-screen video playback is
nice to have, but not a must. I used to have DRI disabled and only the UMS 2D
intel driver enabled.
I think I'll give Chris' shadowfb branch a try, it looks very promising.
Any idea where I can give feedback about it?

When unplugging my mother's Ipod nano it burnt the USB part of the chip,
so almost got there. ;-) I've a Thinpad X40 and it's a wonderful machine,
but it also gives no choice as far as the i855 goes.
