I've checked out Karmic Alpha 3 with Kubuntu using Mesa 7.5 and (I
think) Intel video drivers 2.8.0. There is no more high CPU usage for
idle Xorg. % CPU being used hovers between 0-1%.

[i965] Kubuntu: High %CPU/Power Usage unless downgrade to 2.4 (UXA/EXA)

@bouazza: Yes, I still have crashes, but they're much more infrequent
now (once every 2 days). I did a dist-upgrade after adding the PPA, so
there may have been other packages (most likely mesa) fetched as well.
How are you measuring performance improvement?

Using UXA with Intel 2.7.1 drivers and libdrm 2.4.9, I have reduced
power consumption (13 W) and Xorg in the 2-5% range on idle. 3D
performance is much higher (faster than it ever was), though it's not
reflected in glxgears. There is the X freeze bug every few hours or so,
though.
