The ati driver in U is patched to use EXA and that only works correctly when the kernel module is new enough. With XAA you would not get xv support - but as this the 3d part of the chip has to do that, there will be no further update required, it is just the same.

Well, how well does 2D performance and video work in the radeonhd driver for the 780G chipset (HD 3200)? With fglrx, 2D seems to lag a bit at times, and I dunno if it's related to fglrx, but sometimes when you switch tabs in a multi tabbed session of gvim, the text isn't drawn. However, video seems to work fine with fglrx.

I just want to make sure I've got this straight before I start investing too much thought/time into it: If I were to grab a copy of Ubuntu Jaunty in 2 weeks when it comes out, in theory I'd just have to update xorg-driver-ati/radeonhd and the mesa libs to 7.5, but not have to touch the kernel if I wanted to get the Mesa 3D code for my RV770 working (replace Mesa 7.5 with radeon-rewrite or whatever Mesa branch the code ends up in for now, since it sounds like Mesa 7.5 will be released before all the r600/r700 3D code gets merged in).
Because the item being discussed is Mesa 3D drivers for r600/r700, and there's not yet a Gallium driver written for these chips, no X.Org or kernel updates are needed, just Mesa and xorg-driver-ati or xorg-driver-radeonhd, right?
I've been wanting to try out a lot of the work that's been going on lately for the Radeon 4850 I have in my home machine, but replacing half of the X stack in Ubuntu is a bit more than I really feel like dealing with right now. If it turns out I'll still have to replace X.org and/or the kernel, I'll give it a shot in my Lunar Linux install instead [ yay for source-based distros that aren't Gentoo =) ].
