The V9 kernel patch does in fact let me run Lucid on my Intel 855GME based laptop, which I coudn't before. However, even though xvinfo shows the X-Video Extension with Video Overlay the performance is down relative to Karmic. Both can do 720P video, but Karmic can just keep up with 1080 and Lucid cannot.

On the 1080 video on Karmic I see Xorg at 12% of the cpu with 20% idle headroom.

On the 1080 video on Lucid I see Xorg at 38% of the cpu with 0% idle and it can't keep up.

Any thoughts of why the difference? I can post Xorg logs if that would be helpful.
