>Description:
The x11/xf86-video-intel is old and contains two serious (2.4.x series 
specific) regressions compared to old 2.3.x series.

* Applications using RandR API cause serious flicker in some cases. All GTK+ 
applications are reported to be affected for example.

https://bugs.freedesktop.org/show_bug.cgi?id=17405

* ADD2 cards don't work with 2.4.x driver.
