Hi, mesa maintainers, I've tried to rebuild mesa 10.0.2-1 from experimental with Michal's patch. I were interested only in VDPAU and after week of testing I can say that it works fine on my Radeon HD5670. Both mplayer and flashplugin-nonfree use it and there is no visual glitches with it. CPU load also much lower as it was expected.
Please enable VDPAU in mesa packages. Thanks.
